Version 5.048
| 1. |
Compute: A bug introduced
in version 5.047 for liner with plastic material type is fixed. |
| 2. |
Model: The Piezo
indices were not being updated correctly during cycles of deleting
and adding of the piezometric boundaries. |
| 3. |
Modeler - DXF import of Arcs was
improved. |
| 4. |
Compute: Fixed a strain calculation
problem for 6-noded axisymmetric element. |
Version 5.047
| 1. |
Model: DXF import has
been improved to include support for ARCS and CIRCLES. Polylines
with arcs are now supported. Discretization of arcs is controled
through the Preferences dialog in the File menu. |
| 2. |
Model: Residual tensile
capacity would not be disabled for elastic swellex/split-set
bolts. |
| 3. |
Model: The compressive strength
parameter for the Hoek-Brown failure criterion caused confusion.
This parameter is the unconfined compressive strength of intact
rock. To reduuce the confusion, the label for the parameter
has been changed from compressive strength to Intact UCS. |
| 4. |
Compute: Plate force for Swellex/Split-Set
bolts was not being applied at the face of an excavation. This
is fixed. |
Version 5.046
| 1. |
Interpret. If staged
material properties were defined for a material, the strength
factor calculations would, incorrectly, use the properties
applicable to the previous stage. This is fixed. Files do not
need to be re-computed, but should be re-examined in the Interpreter |
Version 5.045
| 1. |
Model: DXF import of
bolts has been improved. Added option to Preferences "Automatically
clip bolts when added". If
selected, newly added bolts will be clipped to excavation boundaries
and to
stage boundaries. The option is turned off by default. |
| 2. |
Model: DXF Import
and Export of pinned joints was inconsistent with the layer
name. |
| 3. |
Model: Interval on the ruler was
fixed in Modeler. Previously the default
was set to 8 divisions (as for imperial units). Now the interval
is 10
divisions. |
| 4. |
Model: Reducing the number of
stages to 1 when you had liners installed in a stage greater
than one would result in a case where you could not install
the liner in stage 1. |
| 5. |
Compute: For brittle materials
with a residual strength less than the peak, if tensile failure
occurs, the materials strength was not being reduced to the
residual strength envelope. |
| 6. |
Interpret: The units for joint
cohesion were incorrect in the Infoviewer. The problem was
only with
the text displayed for the units in the Infoviewer. The value
shown in the infoviewer, and the results were not effected.
Files do not need to be re-computed. |
| 7. |
Interpret: Effective
Sigma Z was actually showing Sigma Z. This problem was introduced
in version 5.036, and is now fixed. (viewing "szz" user
data was not effected, and the calculation of the strength
factor was not effected. Only viewing "effective sigma
z" was effected). Files do not need to be re-computed,
but should be re-interpreted if results from effective sigma
Z were used. |
Version 5.044
| 1. |
Model: In version 5.043
we broke the pore pressure grid functionality when we fixed
the composite liners. |
Version 5.043
| 1. |
Model/Compute:Previous
to version 5.043, pore pressures were not calculated correctly,
if the model also had composite liners that had a "Composite
Type" that included " with slip". In order to
cause a problem, the composite liner had to be used in the model
(only defining it in the dialog did not cause problems).To fix
the problem read in any old files, re-save, and re-compute the
files. |
| 2. |
Interpret:Fixed the strength factor
calculations in Phase2 interpreter. Lode angle should be limited
to a range of PI/6 and –PI/6 for both Mohr-Coulomb and
Hoek-Brown failure equations. |
| 3. |
Compute: Swellex bolts with zero
residual capacity did not yield thus behaving elastically. |
Version 5.042
| 1. |
Compute: If the value
of the Mohr-Coulomb Tensile strength was being staged (changed
from stage to stage), the program did not use the updated tensile
strength, only the original. Fixed. |
| 2. |
Interpret: When copying liner data,
the coordinates of the nodes are now listed. Previously, only
the node numbers were listed. |
| 3. |
Model: Pinned joint ends is now
the default. Joints that do not end at a free face or another
joint should be pinned. If the ends are not pinned, gaps open
in the mesh and invalid result files can be generated. |
| 4. |
Model: Staging of joint
properties did not work correctly if the joint was part of a
composite liner and there were no natural or artificial joints
in the model. |
Version 5.041
| 1. |
Interpret: Bolt results
would not be read if ".fea" occurred anywhere in the
path (i.e.. if one of the folders had .fea in the name). Fixed. |
| 2. |
Model: Snap did not
work on a vertex that was already selected. This made moving
vertices to coincide with another vertex hard. This is fixed. |
Version 5.040
| 1. |
Compute: Pretensioning
of bolts has been enhanced. In version 5.037, pretensioning
became a boundary condition, meaning the axial force in the
bolt was equal to the pretensioning force at the end of the
installation stage. Prior to version 5.037, the pretensioning
force was applied at the beginning of the stage, but deformation
could affect the final axial force in the bolt at the end of
the stage. Since instances exist where both methods are required,
we now offer a "Constant Force in Install Stage" check
box in the pretensioning area. If the check box is enabled,
the axial force is equal to the pretensioning force at the end
of the installation stage while if the box is unchecked, deformation
will effect the pretensioning force. |
| 2. |
Model/Interpret: File
reading speed has been improved. |
| 3. |
Model/Interpret: When files are
opened, a progress bar now reports the status of the file reading.
Large files would often take a long time to load when the user
pressed the Interpret button in the Modeler. The result being
that the user would think the file wasn't loading or the Interpreter
wasn't working. |
| 4. |
All: Multiple serial number support. |
| 5. |
Interpret: A bug with
the display of axial forces and moments through the "show
values option" is fixed. Sometimes the forces/moments would
be plotted on the wrong side of the excavation. |
Version 5.039
| 1. |
Model: Pore pressures
for the nodes on the edge of an excavated boundary could have
lower pore pressures than expected. To fix the problem files
should be opened, re-saved with the latest version of Phase2,
and re-computed. Only nodes on the boundary between an excavated
region, and a region filled with material are effected. |
| 2. |
Interpret: Improved the warning
dialog for non-convergence in the plasticity calculations in
the finite-element computation. Also added a section to the
help file explaining the possible reasons for non-convergence. |
| 3. |
Model: Improved DXF import and Export.
Program now exports Autocad Polyline entities for exterior,
excavation, material, stage, piezo, and joint boundaries instead
og Autocad Line entities. This makes it easier to transfer DXF
files between Slide and Phase2. |
| 4. |
Model:Pinned and artificial joints
now supported through DXF import. If the joint is not on an
appropriate layer, the program will ask for the type of joint.
New layer names have also been added for pinned and artificial
joints. See the help system for these layer names. |
| 5. |
Model: Program would
crash if the Infoviewer was up and you hit Undo or changed the
number of stages in the Project Settings dialog. |
| 6. |
Model:Materials that
had an Initial Element Loading of "Body Force Only"
or "None", and also had "Custom Load Split"
checked, would act as if they had the load split turned on,
regardless of whether the "Enable Load Split" checkbox
was checked or not. (i.e.. de-selecting the "global"
Enable Load Split checkbox would not turn off the load split
for these materials). The problem would only occur the first
time the file was saved. If the file was opened, and re-saved,
the problem would not occur. |
Version 5.038
| 1. |
Compute: Springs with
plasticity still did not work correctly. They are now fixed. |
2. |
Compute: In some cases,
the pretensioning would not work correctly. This bug was introduced
in version 5.037. |
| 3. |
Interpreter: The drawing
of "show values" was improved for liners. Previously,
if an excavation had liners around the entire perimeter, a gap
would appear in the show values line (the gap would appear between
the first and last points that were entered, when the excavation
was created). The gap does appear anymore. |
Version 5.037
| 1. |
Modeler: "Piezos
by stage" did not show the piezo lines for materials that
used the "peizo to use" setting, but did not have
"stage piezo lines" checked. This only affected the
display in the Modeler; results were not affected. |
| 2. |
Compute: Pretensioning
bolts to a particular load in a stage now ensures that the load
in the bolt at the end of the stage is the pretensioning force. |
| 3. |
Compute: Springs when
used in models with plasticity did not work correctly. |
| 4. |
Compute: Displacements
at a node are now reset to zero if the node is physically removed
from the analysis through excavation. |
| 5. |
Compute: A bug with stiffness formulation
for Swellex bolts was fixed. |
| 6. |
Modeler/Interpreter: Nodal Forces
were not being read from the file correctly, if "stage
nodal forces" was used (via checkbox in the "Nodal
Forces" dialog). Forces are stored in the .fea file as
cumulative values. Previously they were read in as absolute
values, now they are read in (properly) as cumulative values.
Any files that use staged nodal forces are affected by this
change. |
| 7. |
Interpreter: The display of the
values of forces was improved (changed from "%.2f"
to "%g"). |
| 8. |
Interpreter: The "Yielded Elements"
data type now considers shear and/or tension failure in the
solid elements for the calculation of the value. Previously,
only shear failure was considered. |
| 9. |
Interpreter: The "Yielded Elements"
data type did not work properly for differential stages (i.e.
when using reference stages). |
| 10. |
Interpreter: Pore pressure did not
contour properly when there were both piezo lines and infinite
elements used in a model. |
| 11. |
Interpreter: Strength
Factor was calculated using the original material properties,
even if factors were defined for stage material properties.
The staged properties are now used. |
Version 5.036
| 1. |
Interpreter: When plotting queries, you can now choose between effective and total stress, when plotting the normal and shear stress on a line (useful for models with groundwater). |
| 2. |
Interpreter: New user-data variables. |
| 3. |
"evol" - which is the same as the "volumetric strain" data type. |
| 4. |
"emax" - which is the same as the "maximum shear strain" data type. |
| 5. |
Interpreter: Strength Factor is now calculated using effective stress. Previously the calculations had used total stress. Models that had groundwater will have different values for strength factor because of this change. |
Version 5.035
| 1. |
New Feature: Residual strengths can now be defined for both end-anchored and swellex bolts. |
| 2. |
New Feature: In custom load splitting, you can now apply the split to either body forces or initial stresses or both. |
| 3. |
New Feature: You can now Pause the compute engine while it is computing or put it into an IDLE state. |
| 4. |
Compute: Improved the transfer of stiffness from the bolt elements to the solid elements. |
| 5. |
Compute: In some cases, on slower machine, the compute engine would finish but the customer could not open the results for a few seconds. File writing is now better synced with program termination. |
| 6. |
Modeler: Custom Field Stress Properties, and Groundwater properties were only read from the file for the first 10 materials. This is fixed. |
| 7. |
Intepreter: Labelling of the bolt forces (show values) would sometimes not be in the correct location. |
| 8. |
Interpeter: User Data equations greater than 80 characters had problems. |
| 9. |
Intepreter: x,y location added to the list of user data available data. |
Version 5.034
| 1. |
1. Compute: Cable bolt elements did not use the out of plane spacing. Now they do. |
| 2. |
2. Modeler: Having the Infoviewer up while trying to edit geometry caused problems with screen updates and was extremely slow. |
| 3. |
3. Interpret: Polygon fill was not saved to the tools file. |
| 4. |
4. Interpret: Copy of the screen image to the clipboard would clip the legend so that it was not entirely visible (unless it was docked). |
| 5. |
5. Interpret: When plotting horizontal and vertical displacements, the contour range would pick up the sign even though the values are absolute. |
Version 5.033
| 1. |
Compute: Brittle plastic, liners where the residual strength is less than the peak, now properly use the residual strength when they yield. |
| 2. |
Compute: Liners now reported as yield if they break in tension. |
| 3. |
Compute: The staging of liner strength properties for plastic beams did not work correctly. |
| 4. |
Compute: Improvements made to the Cable bolt model to improve accuracy. |
| 5. |
Compute: Sign convention of all the bolt models now consistent. |
| 6. |
Model: Improved the joint properties dialog for staging joint properties. Customers would commonly not set the starting stage for slip resulting in elastic joints even though they had set there joints to be plastic. Now the joint dialog starts the joints out as being plastic in stage 1 for staged properties and plastic joints. |
Version 5.032
| 1. |
Compute: Swellex bolt element that fails in tension was not working correctly. |
| 2. |
Compute: Sign convention for axial force diagram for Swellex bolt was made similar to other bolt models. |
| 3. |
Compute: Delete liner element will crash the engine. This bug is introduced in version 5.03. |
| 4. |
Interpret: Minimum value of shear force diagram for Swellex/Cable bolt was given for wrong location. |
| 5. |
Interpret: Deformation vector and stress/displacement diagram for joint elements were plotted for excavated elements. This bug is introduced in version 5.03. |
| 6. |
Interpret: Joint normal and shear displacement were shown for excavated joint elements. This is fixed |
Version 5.031
| 1. |
Compute: Timoshenko beam elements with midside nodes (used with 6 and 8 noded solid elements) did not work correctly. This bug was introduced in version 5.03. |
| 2. |
Compute: Improvements to the bolt models. A complete check of the code for the bolt elements was done. A verification example, dealing with the split set/swellex model, was added to the verification manual. |
| 3. |
Compute: Pull-out force and pretensioning now works correctly for the split-set/swellex bolts. |
| 4. |
Model: Bolt end points can now both lie on exterior boundary. |
| 5. |
Model: Snap is on by default. |
| 6. |
Model: Reading version 4 files that had sliver elements did not work correctly. |
| 7. |
7Model: Checks for invalid cable bolt data have been added. Specifically, cable diameter=borehole diameter and zero water to cement ratio. |
| 8. |
Model: Boundary conditions for nodes on the exterior boundary that did not exist in stage 1 were not being applied correctly when they came into existence. |
| 9. |
Model: Residual plastic material properties were being updated to the peak values when changes were made to the peak values. This no longer occurs. |
Version 5.03
| 1. |
Model: Fixed a bug with a joint spanning the external boundary. It would not get clipped. |
| 2. |
Model: Made DXF layer naming consistent. |
| 3. |
Model: Improved undo/redo. If multiple instances of the modeler were running, the undo/redo could be corrupted. |
| 4. |
Model: Bolt import from a DXF file would incorrectly switch the end points during the clipping process. This was introduced in version 5.024. |
| 5. |
Interpret: Switched the shear force convention to be consistent with moments. |
| 6. |
Interpret: A note was added to make it clear that differential bolt data is not calculated when doing differential stresses/displacements through the stage settings dialog. |
| 7. |
Interpret: A rare problem with graphing moments in liners was fixed. Sometimes the nodes where not being graphed in the right order according to distance along the boundary. |
| 8. |
Compute: Split set and cable bolts now use relative displacements from the time of installation. |
| 9. |
Compute: Shear forces in liners have been improved by minimizing shear locking. |
| 10. |
Compute: Water and quad elements was not working correctly. |
Version 5.028
| 1. |
Model: Added a new option for applying pseudo-static seismic loading. You can now apply the load in the stage of your choosing. |
| 2. |
Model: When changing the number of stages the load split would be reset. This has been changed such that it is no longer reset. |
| 3. |
Interpret: Graphing and copying data (such as bolt data, or query data) did not work in the last stage for 50 stages models. Only files that used 50 stages were affected. (50 is the maximum number of stages allowed in Phase2 5.0). |
Version 5.027
| 1. |
Model: Material boundaries entered before the existence of an external boundary would crash the program. This bug was introduced in version 5.024. This bug showed up during both material boundary entry and DXF import and is now fixed. |
Version 5.026
| 1. |
Model: Axisymmetric models with materials with custom gravitational field stresses did not work correctly if the horizontal stress ratio was not equal to 1. |
Version 5.025
| 1. |
Compute: If plastic liners were added in any other stage but the first, there existed the possibility that the engine would incorrectly report that a yielded liner did not yield. This resulted in the "Display yielded liners" option in the Interpreter not correctly showing which liners had yielded. This in no way effects the stress, moment or displacement results in the analysis which correctly account for the yielding of the liners. This has been fixed. |
Version 5.024
| 1. |
Model: Stage and material boundaries that are completely outside the exterior boundary are now properly removed. |
| 2. |
Compute: User-defined number of load steps now works correctly. |
| 3. |
Interpret: Maximum value quoted on status bar could be too large when using reference stages (data types affected were: x,y,total displacements, total head, pressure head, pore pressure). |
| 4. |
Interpret: In some cases, files with infinite elements may cause the Interpreter to crash. |
Version 5.023
| 1. |
Model: A bug with how stresses and body forces were handled for elements that change materials between stages was fixed. In all cases the stresses and body forces are reset to the initial element loading state. |
| 2. |
Model: A bug with the reset of the default initial element loading state after using the field stress menu was fixed. |
| 3. |
Model: Residual values of strength parameters are no longer limited to values less than the peak. |
| 4. |
Model: DXF import of material boundaries no longer require the existance of an external boundary. |
| 5. |
Model/Interpret: Initial printing configuration is now set properly. |
| 6. |
Interpret: A bug with the update of contour labels between stages has been fixed. |
Version 5.022
| 1. |
Improved performance for beige hardlocks. |
| 2. |
Update to auto-update code and nodelock code. |
| 3. |
Bug fix for network version and path path dialog. |
Version 5.021
| 1. |
Model: New and improved help system. |
| 2. |
Compute: The Split Set/Swellex bolt model was improved and fixed for cases with face plates. |
| 3. |
Interpret: When using references stages, a graph of a query would not properly label the available plots according to the reference stage. The output graph and data were fine, just a labelling problem. |
Version 5.02
| 1. |
Model: Greatly improved the speed of saving files with pore pressures. If you have multiple stages and files with piezo lines, then saving the file will be a lot faster. |
| 2. |
Interpret: Under certain circumstances, material line geometry would not be clipped correctly resulting in portions of the lines being visible inside excavations. |
Version 5.019
| 1. |
Interpret: ComboBox on Toolbar (to select the visible data) did not show all of the items, if there were a large number of user data items. Fixed. |
| 2. |
Interpret: The "Graph Material Query" dialog could change the contour range, if multiple stages were picked in the dialog, and "copy" was pressed. Fixed. |
Version 5.018
| 1. |
Modeler: Material properties dialog has better error checking when entering values like poisson ratio, angles and dilation parameters. |
| 2. |
Modeler: Files may be written incorrectly for staged joint properties. Load your file into this version, and re-save the file. |
| 3. |
Modeler: Mesh quality toolbar button. |
| 4. |
Compute: Execution priority can now be changed. Useful for running large jobs in the background, while you work with other programs. |
| 5. |
Interpret: Composite Liner data did not list all levels of the composite liner, when copied to the clipboard. Fixed. |
| 6. |
Interpret: Water Symbol Drawing Tool has been added. |
| 7. |
Interpret: Various preferences (Interpret->File-Preferences). |
| 8. |
Interpret: Delete Yield Line option has been added. |
| 9. |
Interpret: Objects that are right-clicked are now highlighted, for better visibility. |
| 10. |
Interpret: Context sensitive help in the dialogs. |
| 11. |
Interpret: EMF/WMF image files now export correctly. |
| 12. |
Interpret: Updated help. |
| 13. |
Interpret: Query All Nodes option automatically creates a point query at each node of the mesh, allowing the user to view the exact interpolated value of the currently contoured variable, at each node of the mesh. |
| 14. |
Interpret: Export Value At All Nodes (File menu), allows the user to export the exact interpolated value of the currently contoured variable at each node of the mesh, to a file. |
| 15. |
Improved license management for network versions. |
| 16. |
Improved look under WinXP. |
| 17. |
A new preferences dialog has been added to the file menu. Using the preferences dialog you can choose the new XP menu style and tabbed views. Tabbed views allow you to quickly change the view through tabs at the bottom of the screen. |
Version 5.017
| 1. |
Modeler: Mapped Meshing would crash the program under certain circumstances. Fixed. |
| 2. |
Composite liners with slip, that span the intersection of a natural joint with an excavation now number the nodes differently. The numbering is such that the liners now span the joint and provide resistance to slip. |
| 3. |
Interpret: A bug in plotting composite liners with slip data has been fixed. Under certain circumstances garbage data was being plotted. |
Version 5.016
| 1. |
Interpret: Fixed a bug on Win9x that the cursor would disappear when adding tools. |
| 2. |
Interpret: Drawing Tools now have an "Apply to All" for making all drawing tools have a similar appearance. (Right click on a tool and select "Format...") |
| 3. |
Interpret: A custom range in Contour Options was not always kept when switching between data types. Fixed. |
| 4. |
Interpret: Fixed link to manuals. |
| 5. |
Interpret: Fixed a bug in Boundary Queries. |
| 6. |
Model: The worst single element for each category is now hi-lighted with a different colour. (See Phase2->Mesh->Mesh Refinement) |
| 7. |
Model/Interpret: Cool XP style menu's on WinXP. |
Version 5.015
| 1. |
Modeler: Staging of material properties for composite liner elements did not work properly. You could not harden or soften the various components. Fixed. |
| 2. |
Compute: Output data files of models with a number of different types of bolt elements (end anchored, fully bonded, cables) would not be written correctly. Fixed |
Version 5.014
| 1. |
Modeler: Under very rare circumstances, tractions would not be applied to the last element along a line segment. |
| 2. |
Modeler: A bug with Undo/Redo was fixed. |
| 3. |
Modeler: Mapped meshing with quad elements would sometimes crash the program. |
| 4. |
Modeler: The status line and right-click context menu's were not updated correctly during edits. |
| 5. |
Modeler: You can now apply relative moves during editing by using the @ symbol when asked for a base point. For example, typing @10,20 for a base point would move the object 10 units in the x and 20 units in the y direction relative to the objects current position. |
| 6. |
Modeler: The Groundwater properties dialog now allows the user to copy the properties from a single material to any other material (instead of all other materials!) through the Copy To... option. |
| 7. |
Modeler/Interpret: Scale factors for tractions has been added back. |
| 8. |
Modeler/Interpret: Printer logic has been changed. Printers are now set up just before printing. This isolates a problem with printing to some HP printers due to a HP driver bug. |
| 9. |
Interpreter: Units for Cable and Split Set bolts are now correct when graphing and when using Show Values. |
| 10. |
Interpret: Tools have been improved. |
| 11. |
Interpret: Snap improved, now can use ORTHO and OSNAP modes similar to Autocad. Toggle them using the status bar. |
| 12. |
Interpret: Export Image now remembers last file type. |
| 13. |
Interpret: If grid and snap were enabled the cursor would disappear. |
| 14. |
Interpret: Defaults for tools (colors, font, line thickness etc.) can now be restored. |

Version 5.012
| 1. |
Compute: Improved the iteration mechanism for the cable bolt model. |
| 2. |
Interpreter/Modeler: Printer is now initialized just before printing instead of when the program starts. |
| 3. |
3Interpreter: A bug was fixed with printer setup. |
| 4. |
4Interpreter: A new pencil tool has been added (Tools...Pencil). |
| 5. |
Interpreter: Custom ruler sizes now possible (View...Ruler). |
| 6. |
Interpreter: Recent directory list has been added (File...Recent Directory). |
| 7. |
Modeler: If a file had a title with a quote in it then the Compute Engine wouldn't run the file. This has been fixed. Just save the file in the modeler again. |
| 8. |
Modeler: A bug in the Groundwater Properties dialog would sometimes crash the program. Fixed. |
| 9. |
Modeler: Fixed a bug when custom load splitting was on for a material. If the split was initialized to 0 it was not being written to the file. This has been fixed. |
| 10. |
Modeler: If the custom load-split was on for a material, body forces were always being written to the file. Fixed. |
| 11. |
Modeler: Mesh quality statistics have been improved in the Infoviewer. |
| 12. |
Modeler: When using Mesh Quality, the worst quality element is now shown. |
| 13. |
Modeler: Fixed a bug in the auto update. |
| 14. |
Compute: Disk space is now displayed correctly. |
