Version 5.044 - Fabruary 01 2010
| 1. |
Compute:A bug introduced
in 5.043 for Cu with depth (see#1 below) was fixed. Models
with Cu with depth and composite surfaces gave incorrect values
of cohesion along the composite portion of the failure surface. |
| 2. |
Model: Improved method for launching
Compute and Interpret from the Modeler.. |
Version 5.043 - September 29 2009
| 1. |
Compute: In the undrained
shear strength model, Cu with depth was sometimes incorrectly
calculated when the failure surface was extremely close to
a material boundary. |
| 2. |
Compute: Models with extremely
thin layers would sometimes crash when geometry was modified. |
| 3. |
Modeler: When reading in a DXF
file with a water surface, the program will now ask you to
assign the water table to a material. |
| 4. |
Interpreter: Grid lines can now
be added to graphs. |
| 5. |
The vertical stress ratio material
model now has the option to define a minimum shear strength. |
Version 5.042 - July 24 2009
| 1. |
Interpret: Colors and
marker styles for Sensitivity plot with multiple variables
are now
consistent.
Previously colors were assigned in order of variables selected
in the Sensitivity Plot dialog. |
| 2. |
Interpret: Fixed legend for Sensitivity
plot. Legend did not always update after selecting different
variables
in Change Plot dialog. |
| 3. |
Compute: In rare cases the non-circular
optimization would result in a surface of higher factor of
safety then the path or block search. This surface would then
be displayed as the global minimum. This is no longer the
case. |
Version 5.041 - July 7 2009
| 1. |
Under rare circumstances
the clipboard would be corrupted. Fixed. |
| 2. |
Excel charting of multiple datasets
would sometimes not work with Excel 2007. |
| 3. |
Security system update to allow
for educational updates and improve commercial network version. |
Version 5.040 - May 4 2009
| 1. |
Modeler: Improved
XSTABL import and added ability to import other STABL files
(e.g.
PCSTABL). Fixed a few bugs with import of geometry, decreased
number of extra vertical lines, improved logic for creating
lower limit, added import of surcharge loads, added import
of TIES, NAILS, GEOSYN, CRACK, BLOCK, circular surfaces and
slope limits. Warnings are now issued for any unknown or incompatible
features. if not specified, units will be determined from u.w.
of water or av. weight of soil. |
| 2. |
Modeler: Added import of GeoStudio
2007 (version 7) files. |
| 3. |
Modeler: Added option not to prompt
to save imported files when closing them - useful when you
only want to view imported file. The option can be found in
Preferences dialog. |
| 4. |
Modeler: For groundwater infiltration
boundary conditions, the seepage face option is now on by default. |
| 5. |
Modeler/Interpreter: Fixed image
drawing that made it disappear at high zoom levels. In modeler
this affected images used for tracing when Pseudo Transparent
or Transparent option was selected. In Interpret it affected
Image Tool with Transparent option selected. |
| 6. |
Compute: Improved the algorithm
for the calculation of segment length for the noncircular path
search. This may result in small factor of safety changes for
files that use a path search. |
| 7. |
Interpret: Improved the generation
of flow lines, the agorithm now uses Runge Kutta integration
with adaptive stepsize. The old algorithm (Euler integration)
sometimes resulted in flowlines that crossed. |
Version 5.039 - February 2 2009
| 1. |
Modeler/Interpreter.
DXF import has been improved and now uses the same code base
as Phase2 7. |
| 2. |
Compute: When doing a probabilistic
or sensitivity analysis with statistics on the water table,
and the deterministic water table was NOT used as the mean
water table, the program would incorrectly calculate the mean
failure surface. |
| 3. |
Interpret. Under rare circumstances
when the failure surface would skim the ground surface, the
program would not draw the global minimum failure surface.
Fixed. |
| 4. |
Model. Permeability functions would
not draw correctly if there was no external boundary. |
| 5. |
Model. Default mesh quality numbers
were changed to match Phase2 7.0. |
| 6. |
Interpret. The program would crash
if tools with dynamic text were imported from another file. |
Version 5.038 - December 12 2008
| 1. |
Modeler/Interpreter.
Optimized for models with very large number of vertices. |
| 2. |
Modeler: New boundary
simplification option has been added. |
| 3. |
Interpret. Fixed bug in Export
Raw Data dialog. Intersections were not exported when checked. |
| 4. |
Interpret. Moved "Reset legend,
display and contour options" from View menu to Preferences. |
| 5. |
Interpret. Black and White settings
for ruler and legend are now saved to registry. |
| 6. |
Compute. Loads on the last slice
ending on a vertical ground surface were sometimes not applied
correctly. |
Version 5.037 - October 28 2008
| 1. |
Model/Interpret: Fixed
seismic symbol position when printing. The vertical position
was fixed
to
top edge of the paper instead of the top edge of the print
margin. |
| 2. |
Interpret: When drawing the global
minimum failure surface in Interpret, you can now change the
color
and line thickness in the Display Options dialog. |
| 3. |
Model/Interpret: Fixed a menu drawing
bug. |
Version 5.036 - September 22 2008
| 1. |
Compute. Improved the
method of generating noncircular surfaces using the block search
and block search windows. The method of randomly seeding points
inside
these block search windows has been improved.. |
| 2. |
Model. Expand/Shrink external has
been improved. If a boundary was completely outside the new
external boundary an error would be generated. Fixed. |
| 3. |
Model. Ponded water in some groundwater
models was not being drawn correctly. Fixed. |
| 4. |
Model. The tooltip for tensile
strength of geotextiles when using imperial units mentioned
metric units. Fixed. |
Version 5.035 - June 12 2008
| 1. |
Compute. Improved accuracy
of the Ordinary/Fellenius method by introducing the Turnbull
and Hvorslev 1967 method of writing the equations. |
| 2. |
Compute. In some rare circumstances,
ponded water would not extend past the default slope limits
even though the water table would. As a result, lateral water
forces due to ponded water would not be properly applied. Fixed. |
Version 5.034 - May 27 2008
| 1. |
Compute: In rare cases,
surfaces generated through material with different saturated
and moist unit weights would not be computed. Fixed. |
Version 5.033 - April 10 2008
| 1. |
Compute. If a failure
surface intersects a tension crack, and a bolt passes through
the vertical portion of the failure surface associated with
the tension crack, the bolt had no effect on the factor of
safety. The bolt was basically ignored. The bolt force is now
added to
the sytem of equations and will have an effect on the factor
of safety. |
| 2. |
Interpret. In some rare circumstances,
compostite surfaces would be drawn incorrectly. They would
pass through the bottom of the external boundary. Fixed. This
had no effect on the results, the compute engine worked correctly. |
| 3. |
Updated Help System. |
Version 5.032 - February 28 2008
| 1. |
Fixed automatic geometry
checking in Modeler. External boundary with overlapping segments
was sometimes allowed to be entered by user. This could results
in mysterious error messages later or even a crash of the application. |
| 2. |
Updated technical support dialog. |
| 3. |
Added new tutorials on tension
cracks and groundwater flow through levees (#15 and #16). |
Version 5.031 - October 10 2007
| 1. |
Interpreter. Fixed
a problem with Favourite Text tool where lines and arrows would
not show up after reading previously saved tools file. |
| 2. |
Interpreter. Fixed problem where
dotted lines on tools would print as solid lines. |
| 3. |
Interpreter. In tools Format dialog
added ability to select any line style for lines with thickness
of more than 1 pixel. |
| 4. |
Interpreter. Fixed a bug with orientation
of discharge section arrows that was introduced in version
5.027. Depending on how they were drawn, some discharge sections
would show flow in the opposite direction. |
Version 5.030 - July 20 2007
| 1. |
New
Anisotropic Linear strength model has been added. |
| 2. |
Improved printing to Adobe Acrobat. |
| 3. |
Modeler: Importing Slope/W files
with more than 20 material properties would crash the program. |
| 4. |
New Help system |
Version 5.029 - April 25 2007
| 1. |
Interpreter:
Zoom to Scale option was removed and replaced by Print to Scale. Scaling
now works correctly for imperial units. |
| 2. |
Interpreter: Added 4 options to control
print out of the model: "Fit View" - default option
which always fits everything visible inside the view window
on to available printing area, "Fit Width" and "Fit
Height" which fit width or height of the view into printing
area, and "Print to Scale" - see below. |
| 3. |
Interpreter: Added "Print
to Scale" option
which allows user to output model on paper to a certain scale.
The scale can be optionally displayed on the print out (go
to Page Setup to turn it on or off). Print to Scale option
can be found under File -> Print Area & Scale -> Print
to Scale menu or on the toolbar. |
| 4. |
Interpreter: More options have
been added to allow the user to save contour, legend and display
options. A defaults button has been added to the contour and
legend options dialogs to allow the user to save certain defaults. |
| 5. |
Interpreter: The default type of
data displayed from a groundwater analysis can now be set in
the Groundwater tab of the display options. |
| 6. |
Interpreter: Ruler now always has
10 divisions between major ticks for both imperial and metric
unit system. Ruler spacing can be easily customized by right-clicking
on the ruler. |
| 7. |
Interpret: Added options to draw
Legend and Ruler in black and white for better looking screenshots. |
| 8. |
Interpret: Transparency and alpha-blending
can now be applied to any type of imported image and not just
bmp. |
| 9. |
Modeler/Interpret: Improved window
tabs for multiple opened files. Tabs now automatically shrink
to fit more tabs in a single row. |
| 10. |
Modeler/Interpret: Page Setup dialog
was simplified and instead of pre-defined and custom formats
the last settings are always remembered and stored in registry. |
Version 5.028 - January 26 2007
| 1. |
Modeler/Interpreter:
Files are no longer opened for writing in exclusive mode. This
sometimes conflicts with network shared drives and certain
antivirus programs. |
| 2. |
Modeler: Fixed a problem where
it was not possible to enter "t" for table of coordinates
or "a" for arc at the prompt line when adding a non-circular
failure surface. |
| 3. |
Compute: If the Janbu Corrected
method was used in a probabilistic or sensitivity analysis,
and another method other than Bishop or Janbu was also used,
the program would mix up the statistical/sensitivity data. |
| 4. |
Compute: Back analysis of steeply
dipping surfaces in clay would result in wrong results for
the active or passive load. This due to m_alpha checks not
being properly applied. Fixed. |
| 5. |
Compute: The elevation surface
option with multiple slope limits did not work correctly for
circular surfaces. Fixed. |
| 6. |
Compute: Circular surfaces now
check that there are enough slices to handle all soil material
intersections with the surface. This will help you improve
the accuracy for models with huge numbers of material boundaries. |
| 7. |
Interpret: The picture format is
now saved to the registry. As a result, when you start Interpret,
the last setting of Picture Format is remembered. |
Version 5.027 - October 16 2006
| 1. |
Modeler/Interpreter:
Zoom To Extents now takes into account Line load, Distributed
load and Infiltration arrows. |
| 2. |
Modeler: Added warning when ratio
of the model coordinates to the model dimensions is too large.
Warning appears after adding an external boundary either manually
or from a DXF. |
| 3. |
Modeler: Added "Restore All
Warning Messages" option to Preferences. This allows to
restore warning messages previously hidden with "Don't
show this message again" option. |
| 4. |
Interpret/Compute: Discharge section
on a boundary could cause a crash. |
| 5. |
New Help system was added with
new verification examples and manual. |
Version 5.026 - August 8 2006
| 1. |
Modeler: A new option for the
adding of a linearly varying head boundary condition in a groundwater
analysis has been added. |
| 2. |
Modeler: A new option for ungrouping
support patterns has been added. This allows you to add a pattern
then indiviually change a particular bolt in the pattern. Added
menu option and right-click shortcut to ungroup Support Pattern
into individual support items |
| 3. |
Modeler: Bolts that are touching
external with both ends could reverse their direction after
adding a new anchor. Problem was fixed and bolts are now drawn
with a faceplate on the first end. |
| 4. |
Interpret: "Enlargement factor" option
was missing from Image Export feature for charts |
| 5. |
Modeler: Changed default color
of mesh elements to light gray. The color can be changed in
Display Options (and the setting is remembered). |
| 6. |
New Help system was added with
new verification examples and manual. |
Version 5.025
| 1. |
Compute: Distributed
loads located inside a material/slope (not on the slope surface)
but outside
a failure surface would be applied to the failure surface under
certain circumstances. This
is fixed. |
| 2. |
Interpret: In the case of ponded
water, the seismic load plot would incorrectly use the water
weight. This is a graphing issue only, the compute engine correctly
removes the weight of water from the seismic load calculation.
The factor of safety results are not effected. |
| 3. |
Interpret: In probabilistic mode
when plotting histograms of data, and the secondary data was
factor of safety<some number, invalid surfaces would be counted
and displayed as failed surfaces on the plot. The numbers in
the title of the plot would also be incorrect. |
| 4. |
Interpret: Strength function markers
and values are now displayed in front of the supplemental contours. |
| 5. |
Interpret: In certain circumstances,
the type of water surface assigned to a material would not
be displayed incorrectly in the Infoviewer or data tips. |
| 6. |
Interpreter: Fixed precision issue
in tools file. The precision for location of tool objects was
not adequate. This especially affects contour labels. |
| 7. |
Interpret: Under certain circumstances,
secondary contours of strength would sometimes come up blank.
This is a graphing issue only and the factor of safety numbers
are correct and use the correct strength. |
| 8. |
Model: When adding a water table
in statistics mode, the assign dialog would sometimes not appear. |
| 9. |
Model/Interpret: Improved Toolbar
code. |
| 10. |
Model: Tab stops in the material
and bolt property dialogs were improved. A small text truncation
issue in the distributed load dialog was also fixed. |
Version 5.024
| 1. |
Compute: Tension cracks
under ponded water did not work correctly when the water depth
in the tension crack was defined with any method other then
the water table method. The hydro force in the tension crack
now completely determines the force on the left/right side
of the failure surface. The filled, filled to depth, filled
below elevation, and percent filled now work correctly under
ponded water. The
depth of the tension crack now extends to the top of the ponded
water. |
| 2. |
Compute: The thrust line was not
computed correctly for left to right surfaces with ponded water
on the left or right side of the surface. |
Version 5.023
| 1. |
Compute: Excess pore
pressures were being generated in regions where the initial
pore pressures were negative or zero. Now excess pore pressures
are only generated in saturated (initial pore pressures > 0)
regions. This only affects B-bar analyses (see the Groundwater
tab in the Project Settings). |
Version 5.022
| 1. |
New help system including
new, improved, and updated tutorials. New startup dialog for
people that are new to the program. New start menu. |
| 2. |
Interpret: A new option called
Show Coordinates has been added to the View menu. Coordinates
of all the vertices can now be toggled on/off quickly using
this option. A good option for quickly annotating your output
with the vertex coordinates. |
| 3. |
Model/Interpret: All the vertex
coordinates are now automatically added to the InfoViewer.
This is for people who have to supply coordinates in their
technical reports. If you wish to turn them off, use the option
in the Preferences dialog. |
| 4. |
Compute: With the B-bar excess
pore pressure option, the self-weight of a material can now
generate its own excess pore pressure. This allows you to combine
pore pressure due to a water table with pore pressure due to
Ru effects. |
Version 5.021
| 1. |
Model: Fixed a bug
in the mesh generation for groundwater models. This bug was
introduced in version 5.02 and would result in elements that
incorrectly crossed boundaries. |
Version 5.020
| 1. |
Groundwater Compute:
Improved groundwater analysis algorithm for seepage faces. |
| 2. |
Compute: Now checks for ponded
water below the left or right surface intersection point. It
then does not include the unit weight of this material in the
calculation of the hydrostatic water load on the left or right
side of the surface. |
| 3. |
Model: Improved Seep/W file exporter.
Better support for generating the model in Slide and exporting
a file that runs in Seep/W. |
Version 5.019
| 1. |
Groundwater Compute:
The engine will check to see if there is flow into the model
from the unknown boundary condition type. The unknown boundary
condition will be converted to zero nodal flow for such cases. |
| 2. |
Model: When groundwater finite-element
modeling, deleting vertices could result in future incorrect
discretization
of boundaries when meshing and a resulting bad mesh. |
| 3. |
Model: Improved Slope/W 4 and 5
file reader. Added support for GeoStudio 2004 files. |
Version 5.018
| 1. |
Under very rare circumstances
which almost always is associated with an optimized surface,
the weight of a slice was inaccurately calculated. |
Version 5.017
| 1. |
Now supports multiple
HASPHL locks on the same USB hub. |
Version 5.016
| 1. |
Modeler: In certain
cases boundaries were not intersected properly and overlaps
were
not automatically
fixed by Slide. This resulted in geometry error messages and
sometimes prevented user from running Compute. |
| 2. |
Modeler: "Automatically fix
boundary overlaps" option in Preferences was removed.
Material boundary overlaps are now always fixed. |
| 3. |
Modeler: File Import for certain
Slope/W files would abort with error "Could not read file".
Fixed. |
| 4. |
Modeler: Geometry would not import
correctly for certain Slope/W files. Fixed. Overall improvement
of Slope/W file reading. |
| 5. |
Modeler: If you set the file to
be probabilistic (or sensitivity), then defined a water table,
the assign dialog to apply the water table to the materials
is not shown. Fixed. |
| 6. |
Modeler/Interpret: The three groundwater
levels for sensitivity or proabability analyses were shown
if you reverted back to deterministic mode. Fixed. |
| 7. |
Modeler: The grid used for drawing
is now saved to the registry so that when you restart the program,
the grid settings you were using are restored. You can now
restore the program default grid settings through a default
button in the grid dialog. |
| 8. |
Compute: Modified Chugh's method
of grid interpolation could result in wrong extrapolated pore
pressures. Fixed. Also improved the interpolation/extrapolation
of coarse grids of sample points. |
| 9. |
Modeler/Compute: Added the ability
to use convex surfaces for optimization. See the optimization
settings dialog. |
| 10. |
Modeler/Compute: Added the ability
to use the convex surface setting during optimization. See
the optimization settings dialog. |
| 11. |
Modeler/Compute: Added the ability
to use the min depth and min elevation during optimization.
See the optimization settings
dialog. |
| 12. |
Modeler: Improved DXF import of
files with multiple overlaps of line segments.. |
| 13. |
Modeler/Compute: Added the ability
to use the min depth and min elevation options for block searches. |
| 14. |
Modeler/Interpret: Menu checkmarks
would sometimes not be rendered correctly. |
| 15. |
Interpret: Added the ability to
plot more accurate and detailed pore water pressure and discrete
strength function contours through the supplemental contours
option. The old algorithm would sometimes produce coarse inacurate
contours when a lot of sample points existed. |
Version 5.015
| 1. |
New Hasp-HL hardlock
support. Removed support for old beige hardlocks. |
Version 5.014
| 1. |
"Copy (Slide Modeler
Format)" in SlideInterpret, and "Edit->Paste from
Interpret" in Slide now work for circular surfaces. Previously
this functionality was only available for non-circular surfaces. |
| 2. |
Interpret: If a circular surface
was input, and then the surface type was set to non-circular,
the
circular
surface could, sometimes, still be visible in the Interpreter.
This is fixed. |
| 3. |
Interpret: In rare instaces, optimized
surfaces that hit the bottom boundary of the model would not
load correctly
into the Interpreter. |
| 4. |
Compute: Optimization with an option
of optimizing failure surfaces with a factor of safety under
a
certain value would sometimes not properly display the optimized
surface in the Interpreter. |
| 5. |
Modeler: In the Fredlund and Xing
Hydraulic Parameters selection dialog, the units displayed
were incorrect
for
the A and C parameters. The actual values were okay, it was
just the text in the dialog that was wrong.
|
Version 5.013
| 1. |
The Barton-Bandis strength
criterion has been updated to include the 70 degree maximum
at low confining stresses (Barton and Choubey 1976). Phib has
also been changed to Phir to better represent the current criterion.
The help has been updated as well. |
| 2. |
Compute: A problem with the optimization
not including the distributed load in certain situations was
fixed. In particular, if the load was on a vertical face. |
| 3. |
Compute: In rare situations,
Janbu corrected, coupled with a circular analysis, would yield
a
problematic
file. |
| 4. |
Interpret: Supplemental contours
(Interpret->Data->Supplemental Contours->Setup)
would not display "phi" contours properly for the
first discrete strength function defined, if the function type
was "drained" ("c" contours would be displayed
instead of the "phi" contours). Only the supplemental
contours for materials with a "discrete function" strength
type were effected, the factor of safety calculations were
not effected. Files do not need to be re-computed, only viewed
again in the Interpreter. |
| 5. |
Compute - There was a small improvement
in an iteration component of the surface optimization algorithm.
The final step of the optimization was improved, so that a
better (i.e. lower FOS) surface will be picked. Typically this
will only result in a change of factor of safety of less than
0.00001, but some (very sensitive) models may experience better
results (change in FOS ~ 0.04). At all times, the results that
were displayed were correct. |
Version 5.012
| 1. |
Compute: Loads on vertical
slope faces might not be applied correctly during optimization. |
| 2. |
Compute: The interslice normal
force associated with a vertical slope face with an applied
load is now set correctly to the value of this load. This has
no effect on the factor of safety results. |
| 3. |
The point focus for a non-circular
failure surface has been improved. You can now set it on the
toe of a slope and have surfaces generated. |
Version 5.011
| 1. |
Compute: Improved the
iteration mechanism for deeply submerged slopes. |
| 2. |
Interpret: Saving a tools file,
while in the midst of adding the first drawing tool to a view,
would create an invalid tools file (an error message would
be display the next time the file was opened). This is fixed. |
| 3. |
Support for new Educational system.
Also update dll's to latest microsoft versions. |
Version 5.010
| 1. |
B-bar method added
for excess pore pressure modeling |
| 2. |
Can now combine Ru with water surfaces |
| 3. |
New material model that combines
drained and undrained material parameters. |
| 4. |
Interpret:The favourite text entry "Coordinates
(3 decimal places)" did not display the y coordinate properly.
This is fixed. |
| 5. |
Model: A bug with importing water
tables using DXF files was fixed. Also improved the documentation
on the subject. |
| 6. |
Air Entry value for unsaturated
shear strength can now be defined. |
| 7. |
Rapid drawdown analysis
using the B-bar method. |
Version 5.008
| 1. |
Compute: In certain
cases, running batched computes of probabilistic files would
not compute properly. This is fixed. |
| 2. |
Compute: The batch folder-loading
( Alt-F ) in Slide Compute, will now write a batch file to test
against the existing batch folder-loading (in order to identify
"batch compute" vs. "multiple individual computes"
bugs). In the Interpreter, type "comparefolders" on
the command line, and pick the two folders to generate the report.
The folder loader is now in the system menu as well. |
Version 5.007
| 1. |
Interpret: "Multiple
surfaces at this location" dialog is now shown much less
frequently for "standard" data output files ".
The Interpreter will automatically pick the appropriate surface,
when possible. |
| 2. |
Model: Previously, if the file extension
had any capital letters,
the Interpret button would not be enabled. The Interpreter could
still be started
and load the file, but the button in the modeler would not be
enabled.
This is fixed. |
| 3. |
Model/Interpret: Restricted
users could not set the Page orientation in Page Setup dialog.
Fixed. |
Version 5.006
| 1. |
Model: Import of Slope/W
files is much improved: i) Slide will now import files written
by Slope/W version 5 (previously only version 4 files were imported).
ii) Slide will now import Slope/W *.slz files, as well as the
existing *.slp files. iii) The filter in the Open-file dialog
was improved, to display all files that Slide can open (so "Files
of type" doesn't have to be used). iv) The "material
was renamed" warning that appeared if the lowest material
was named "Bedrock" has been removed. v) Analysis
Methods (eg. Bishop, Janbu, etc) are now imported. vi) Blocks
are now imported, and converted to Slide's block search Point,
Line or Window (as appropriate). |
| 2. |
Model: When importing Slope/W files
with a grid of total head as the pore-water pressure option,
the last entry in the grid would be missed. This is fixed. |
| 3. |
Model: The right-click menu for
non-circular surfaces now has an option "Copy (list of
coordinates)" When this option is selected, the list of
vertices forming the slip surface is placed on the clipboard.
This tabular list can then be pasted into Excel, or another
program. This option is especially useful for comparing surfaces
in different slope stability packages. |
| 4. |
Model: "Show Coordinates"
in the Slide Modeler, has been much improved. Once objects are
picked for show coordinates, the coordinates are listed in the
Infoviewer. The Infoviewer is formatted with tabs, so the list
can be easily pasted into a spreadsheet. Decimal place formatting,
and selecting of specific objects is controlled by the show
coordinates dialog. |
| 5. |
Model: Fixed check for overlapping
segments that would sometimes erroneously report that boundary
segments overlap for models where 2 vertices are located too
close to each other. |
| 6. |
Model: Improved speed of geometry
check routines for models with very large number of materials. |
| 7. |
Model: In DXF import, fixed a bug
when polylines from layers other than the one specified could
be imported. This could happen only if a single boundary was
selected for import and the DXF file contained layer names not
importable by Slide. This fix also improves the speed of import
from such DXF files. |
| 8. |
Model: Added option to ignore all
errors when importing DXF file. If a warning dialog with an
error pops up during DXF import, user can choose not to show
any more warnings and continue importing file. |
| 9. |
Model: Improved the DXF import. |
| 10. |
Model: In very rare cases, when
vertices on the exterior boundary are very close together (fraction
of a millimetre), the program would create empty zones within
the slope. These zones have a white color and could not be assigned
material attributes. |
| 11. |
Model: Added a note at the bottom
of Water Pressure dialog: "NOTE: Pore pressure data can
be contoured using Supplemental Contours option in Interpret" |
| 12. |
Model: Fixed a problem where Slide
could crash after deleting an external boundary. |
| 13. |
Model: For boundary input using
Coordinate Table, the requirement to input at least 3 points
for External boundary and 2 points for material boundaries was
removed. |
| 14. |
Model:Fixed a bug in the security
class for nodelocking of customers with a userid<100 |
| 15. |
Interpret:An uninitialized memory
error was fixed. |
| 16. |
Interpret: Part 2 of
the verification manual was added to the help menu. |
Version 5.005
| 1. |
For the Generalized
Hoek-Brown failure criterion, GSI, mi, and D can now be defined
as random variables in a probabilistic or sensitivity analysis.
To do this, use the GSI calculator dialog in the material properties
dialog and check the box stating that you want GSI, mi and D
to be random instead of mb, s, and a. |
| 2. |
Model / Interpret: Change: Metric
units are now properly listed as "kN"
and "kPa" instead of "KN" and "KPa",
in accordance with the official SI
standards. |
| 3. |
Model: The coordinate
table option in the right-click menu has been moved down the
list. Often people would click this option when wanting to specify
done. |
Version 5.004
| 1. |
Compute: The Optimize
Surfaces Settings dialog now offers an option "Snap Shallow
Surfaces to Slope". The optimization occasionally formed
surfaces that had unrealistically shallow sections, near the
start or end of the surfaces. This option will remove these
sections of the surface, resulting in a more realistic failure
surface. The distance criteria used for the snapping is calculated
automatically, or it can be specified in the dialog by checking
the "Specify Distance" checkbox. |
| 2. |
Groundwater Compute: Anosotropic
permeabilites with an angle other than zero degrees did not
work correctly. |
| 3. |
Model: Added Seepage
face option to the infiltration and nodal flow boundary condition
for groundwater finite element analysis. This additional boundary
condition will ensure that the total head at a node does not
exceed the elevation head. |
| 4. |
Model: Added coordinates table for
boundary entry. While adding a
boundary user can bring up a table to easily enter all the coordinates
of
the boundary. Coordinates can be typed in manually, pasted from
a
spreadsheet program or imported from a file. |
| 5. |
Model/Interpret: Added/Fixed printer
setup option. A Printer Setup
button was added to Page Setup dialog. It gives a user the ability
to select
a different printer, paper size and other printing options.
The printer
settings are remembered until user quits the program. |
| 6. |
Model: Fixed zoom on right click.
Sometimes after panning, a right
mouse click would do zoom in on window. |
| 7. |
Compute: Added tensile strength
to the power curve strength model. |
| 8. |
Model/Interpret: Updated the Help
files. |
| 9. |
Interpret: De-selecting groundwater
mode, when there are no slope stability results available caused
problems. |
| 10. |
Model: Statistical properties for
materials and anchors were not imported (using File->Import->Properties,
or using the default properties file) along with the standard
set of properties for each material or anchor. The problem is
now fixed. |
| 11. |
Model: Bug fix where correctly entered
material or tension crack boundaries could be rejected by the
modeler with the error message "Material and tension
crack boundaries must lie within the external boundary". |
| 12. |
Model: Improved DXF import and Export. |
| 13. |
Model: Pore water pressure grids
(PWP files) now allow the import of DXF files containing lines
and polylines. The line/polyline vertices are entered as points
in the grid. |
| 14. |
Model: Fixed a bug where Infiltration
of 0 was not saved to the file. |
| 15. |
Model/Interpret: Fixed a bug where
a dialog window could suddenly crash. |
| 16. |
Interpret: Five new data types for
Finite Element Analysis groundwater models: Horizontal, vertical
and total hydraulic gradients; horizontal and vertical permeabilities.
User data variables corresponding to these data types (ix,iy,it,permx,permy)
were also added. Existing Slide files must be re-computed (with
Slide Compute 5.004 or later) to view any of these data types. |
| 17. |
Interpret: The Infoviewer
did not list groundwater material properties, when the slope
stability results were being viewed. This is fixed. |
| 18. |
Groundwater Compute: Saved files
with a single or double quote in the title would not run correctly.
The modeler now strips the quotes from the job title. |
| 19. |
Interpret: When closing
multiple files with added tools, the program would only ask
to save the tools for the first file. |
| 20. |
Interpret:There is now an option
(Groundwater->Export->Allow Suction Pressures) to control
suction pressures during the export of Phase2 pwp files. If
this option is checked, the values are written to the file without
modification. If this option is unchecked, all negative values
are set to zero. |
| 21. |
Interpret: Drawing in the Interpreter
could be very slow if a model had many (1000+) surfaces, all
with identical locations and identical factors of safety (eg.
a model that had a 5000 surface block search, with two block-search
points). |
| 22. |
Model/Interpret: :When
using FEA as the groundwater model, the datatips (the yellow
text, that appears as you hover the mouse over a material) would
list "Ky/Kx Ratio". The text should have been "K2/K1
Ratio", as is entered in the dialog. Only the datatip display
was incorrect; the computation and results were not effected. |
Version 5.003
| 1. |
Model/Interpret: Better
handling of large coordinates in models. |
| 2. |
Model: Two discrete
functions could be defined with the same name leading to unpredictable
results. |
| 3. |
Compute: Tangent line
now works for slope search. |
4. |
Compute/Interpret: Overall
slope reliability when the minimum surface is the same and goes
through a material with non-random strength properties would sometimes
yield an unreadable data file. |
| 5. |
Compute/Interpret: Error
codes -119 (non-circular surface above tension crack zone),
and -120 (tension on the base) were added. |
| 6. |
Compute: Fixed a bug
which would crash the program if the sensitivity of certain
bolt parameters was attempted. |
| 7. |
Compute: Effective tensile stresses
on the base of a slice that exceeded the tensile strength for
non-linear failure models (Hoek-Brown, Power Curve, Barton-Bandis,
Hyperbolic, Shear-Normal Functions) were not being handled correctly.
This resulted in data files that could not be read by the Interpreter. |
| 8. |
Compute: For non-linear failure
envelopes (Hoek-Brown, Power Curve, Barton-Bandis, Hyperbolic,
Shear-Normal Functions), improved the iteration and convergence
checks. |
| 9. |
Modeler/Compute: Added the ability
for users to define an advanced error check to look for effective
tensile stresses on the base of slices and throw away surfaces
that have these tensile stresses. This check is not on by default
but can be turned on in the Methods…Advanced dialog in
the Project Settings. |
| 10. |
Interpret: If two discrete
functions were in the data file but the first one wasn’t
used for a material, the Interpreter would not contour the functions
correctly. |
| 11. |
Interpret: Composite surfaces were
sometimes not drawn correctly. |
| 12. |
Interpret: Right-clicking on a single
surface would not give the option to plot the data associated
with the surface. |
| 13. |
Interpret: Plus sign added to the
final contour interval for safety factor contours. This is to
make sure customers understand that the last interval includes
all safety factor data to infinity. |
| 14. |
Model/Interpret: Updated the Help
system. |
Version 5.002
| 1. |
Model: When adding a
valid Maximum water table, the program would incorrectly give
error message that the boundary must be above. |
| 2. |
Model: When switching to Groundwater mode, statistical Min, Max, and Mean water table boundaries were not deleted. |
| 3. |
Model: If the user changes
number of elements in Mesh Setup dialog and then clicks on Mesh
button in the dialog, the model is not rediscretized before
meshing. |
| 4. |
Model: In Demo version,
it is probably confusing to the user why Undo/Redo is disabled
after they perform any action. Added "(Disabled in Demo)" text
to all disabled menu items in the Demo version. |
| 5. |
"Don't show me this" flag for Demo Startup dialog was saved to a file in the application folder. Now saved to the registry. |
| 6. |
Compute: On very rare occasions Compute engine might crash at the very end of computation. |
| 7. |
Fixed problem with commercial network nodelock. |
