  14. Modeler: In Add Vertex mode Snap option was applied always, even when coordinates were entered through prompt line. This prevented users from entering new vertices close to existing vertices. Also there’s now a message telling user if inserted vertex already exist instead of generic message “Point is not on any boundary”.
  15. 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.
  16. Interpret: Added the ability to plot major prinmciple stress flow lines. Look in the Analysis menu under Stress Flow.

  6. For structural interfaces and composite liners, ability to apply water pressures in joint to only an adjacent liner (and not to surrounding continuum / solid elements).
  7. Application of distributed loads directly to liner or structural interface elements. When distributed load is applied, if a Liner or Structural Interface is active in that stage, it will applied directly to liner element, otherwise it will be applied to the solid element.
  8. Ability to use effective stress ratios for models involving finite element seepage analysis.
  9. Improved tolerance and iteration factors for SSR analyses.
  10. Improved help system including new tutorials.
  11. Modeler/Interpreter. Data tips state is applied to ALL documents instead just the current one.

  14. Modeler/Interpreter. Page setup settings were not saved after a program exited.
  15. Modeler/Interpreter. "Show Coordinates" feature has been added to both Modeler and Interpreter. All boundary coordinates are displayed in the Infoviewer by default. This can changed in Preferences. Coordinates can also be displayed on screen for all or selected boundaries.
  16. Modeler. Added option to change Structural Interface orientation. Also added display options to show Structural Interface's orientation and expand structural interface's display to its components.

  24. Modeler. Added option to automatically add midside nodes to imported Slide models with FEA groundwater.
  25. Modeler. Fixed automatic bolt installation/uninstallation. Sometimes changing installation stage of a bolt would randomly change installation stage of another bolt.

  27. Interpreter. Maximum Shear Strain was calculated incorrectly for axisymmetric models.

Version 6.006

  1. Gravitational stress fields with both ground surface elevation and effective stress ratios defined gave garbage results. If the actual ground surface was used with effective stress ratios, then the results were fine. Fixed.

Version 6.005

  1. Now supports multiple HASPHL locks on the same USB hub.
  2. Compute: Duncan-Chang materials would sometimes crash the compute engine. Fixed.
  3. Interpret: Normal and shear displacements on a joint did not plot at all.

Version 6.004

  1. Compute: Pressurized joints incorrectly accumulated the pore pressure from stage to stage. Fixed.
  2. Added HASPHL hardlock support
  3. Interpret: In some very rare cases, the display of factor of safety for Generalized Hoek-Brown materials was incorrect.

  2. Model: Improved the way restraints are restored on external boundary when remeshing.
  3. Model: Additional pressure inside a joint option did not work correctly.
  4. Compute: Pressurized joints did not work correctly.

  10. Interpret: The command prompt text shows up in bold now just like in Modeler.

Version 6.002

  1. Model/Interpret: Faster file reading. Interpret is now faster when switching stage tabs and when switching data type. Especially if there are joints or structural interfaces in the file.
  2. Model: Load splitting coupled with effective horizontal stress ratios for gravitational initial stresses did not work properly. Fixed.
  3. Model: Pore pressures defined using grids or Ru factors were not split when using load splitting. Only pore pressures defined using piezo lines were split correctly. Fixed.
  4. Model: Bolts that cross elements that were attached to joints or structural interfaces did not work correctly if elements on either side of the joint were excavated.
  5. Model: GHB materials during import of Slide files are given a default modulus more indicative of rock.
  6. Model: The import of Slide files would sometimes crash. Fixed.
  7. Model/Interpret: Print Header/Footer did not work correctly when metric units were used. Fixed.

  9. Model/Interpret: Menu checkmarks would sometimes not be rendered correctly.
  10. Compute: Acceleration of the SSR analysis by reducing the number of iterations after failure was removed. It would create odd looking (although not inaccurate) results.
  11. Compute: Pretensioning of swellex bolts did not work correctly.
  12. Model: Phase2 would crash if Enter key was pressed with Infoviewer up.
  13. Interpret: The material name of an excavated region in the Infoviewer was not correct.
  14. Interpret: Changed default animation time to 0.5 seconds instead of 0 seconds.
  15. Model: Internet update would crash the modeler.
  16. Model/Interpret: Hatching of ponded water when joints existed did not work correctly.

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. Compute: Cable bolt elements did not use the out of plane spacing. Now they do.
  2. Modeler: Having the Infoviewer up while trying to edit geometry caused problems with screen updates and was extremely slow.
  3. Interpret: Polygon fill was not saved to the tools file.
  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. 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. Model: 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 5.021

  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.

  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...")

  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.

  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.
