Updates

Repeated stage regeneration for phases using groundwater flow can give incorrect pore water pressures

When generating a new mesh for an already defined model, the Plaxis 2D software will regenerate all phase settings, recalculate the pore pressures based on a phreatic level and perform the K0 analysis. Pore pressure distributions based on groundwater flow analyses must always be recalculated manually.
The behaviour works as intended for projects that do not use groundwater flow, and in cases where the regeneration is performed once.
However, if a project contains defined phases that use groundwater flow and its mesh is regenerated several times (e.g. for mesh refinements), the stage regeneration sometimes mixes up the type of pore pressure generation, which can lead to incorrect pore pressures for any phase. Should your project use groundwater flow, we strongly recommend making manual recalculation of all pore pressures and K0 procedure a part of your normal phase consistency checking following an automatic stage regeneration.

If you have projects with very large numbers of phases, please have a look at the speedup possibilities offered by the tip in the FAQ section. This option will also reset all phases to use phreatic level calculation. In this case it is sufficient to recalculate pore pressures only for the phases that need to be switched back to groundwater flow.

This issue will be addressed in the next major release of PLAXIS 2D.

Release notes:
This update can be used for PLAXIS 2D Version 9 only.
All changes made in previous Updates have been incorporated in Plaxis 2D Version 9.02. This Update is a self-extracting and installing package. After downloading, please run it and follow instructions.

As part of the Plaxis 2D Suite, this update also contains PlaxFlow Version 1.6

New Features

New features in Plaxis 2D Version 9.02

• In Plaxis 2D Version 9.02 the stage regeneration has been improved. Not only changes in materials, but also in load values or displacement values made in the Input module prior to the mesh generation will be incorporated for all consecutive phases as long as the configuration does not change from the initial configuration.

New features in Plaxis 2D Version 9.01

• Apart from the English language pack, Version 9.01 introduces the Chinese and Japanese language packs. For resetting the language, the user must run the PLAXIS 2D Version 9.01 Input program and press CTRL+SHIFT+ALT+R. After restarting PLAXIS 2D, the user may choose the desired language.

New features in Plaxis 2D Version 9.0

• Hardening Soil Small Strain Stiffness model
• Stage Regeneration
• Soiltest Oedometer test
• Soiltest Triaxial Test
• Geometry Consistency Check
• User Action Logging
• CodeMeter Hardware Dongle

Bug Fixes

Fixes in Plaxis 2D Version 9.02

• In Plaxis 2D 9.01, the combination of a non-linear phase tree and the deletion of a lot of phases leads to a 'Phase Index out of Bounds'-error. In Plaxis 2D V9.02 this problem has been fixed.
• The regeneration of a combination of closed flow and closed consolidation boundaries in Plaxis 2D 9.01 leads to incorrect boundary conditions. This is solved for Plaxis 2D version 9.02.
• In Plaxis 2D Version 9.0, there was some confusion about mesh regeneration after a load change, done in the geometry input. Plaxis 2D Version 9.02 deals with this more user friendly.
• Certain combinations of your general settings could lead to unreadable rulers. This problem has been fixed for Plaxis 2D Version 9.02.
• When choosing the variable 'time' in the Soiltest-application, Plaxis 2D selected the variable 't' instead. In Plaxis 2D Version 9.02 this has been solved.
• Sometimes, when Plaxis Input is being closed, the program gives an Application Error ("The memory could not be read"). This problem has been fixed for Plaxis 2D 9.02.

Fixes in Plaxis 2D Version 9.01

With PLAXIS 2D Version 9.01, these bugs are fixed:

• The report generator didn't work in version 9.0. In Plaxis 2D Version 9.01 this has been fixed.
• In Plaxis 2D Version 9.0. during a phi/c reduction, the strength of wall elements will also be reduced. In version 9.01 only the soil reduction, as described in the manual, is taken into account.
• In Plaxis 2D Version 9.0, there was some confusion about mesh regeneration after a material change, done in the geometry input. Plaxis 2D Version 9.01 deals with this more user friendly.
• Changing multiple point loads in Plaxis 2D Version 9.0 didn't work properly. This has been fixed in Plaxis 2D Version 9.01
• The groundwaterflow kernel of Plaxis 2D version 9.0 scales the discharge values for some combinations of well properties, soil permeabilities and model sizes. After the calculation, these values are not scaled back. This could lead to strange discharge values in the results. Plaxis 2D version 9.01 contains a new groundwaterflow kernel which solves this problem.

Known Issues in Plaxis 2D Version 9

• Plaxis 2D V9 is significantly stricter on the data structure than Plaxis 2D V8.6 was. Therefore, it is possible that version 9.0 can not read version 8 projects. In version 9.01 some of these reported issues have been fixed. However, if Plaxis 2D still fails to read an old project, you can send it to the Plaxis support department. We can do the conversion at the Plaxis office and we can use these project to improve the compatibility with version 8 in the next update.
• The "Pack Project" option as it was implemented in Plaxis 2D Version 8 unfortunately had some issues where sometimes not all files were packed or corrupted during the pack process. After investigation of the problem, it was decided that the best solution would be to completely make the option from scratch instead of trying to fix the issues. In order to prevent that users can still pack projects that may not be able to unpack, the option has been disabled in Plaxis 2D Version 9. However, previously packed project can still be unpacked with Plaxis 2D Version 9, in the Input program. In the next version of Plaxis a new "Pack project" will be available. If development of the option goes well, we will even release it earlier than that as a stand-alone (free) update of the software.

Project compatibility

• Due to a difference in the handling of files since Plaxis 2D Version 9.0, files made with this version, or newer, cannot be read in Plaxis Version 8.6 or older.
• Plaxis 2D Version 9.0 and later is able to read projects created with Plaxis Version 8.2 with update pack 4 or newer.
• Also, the interaction with PlaxFlow Version 1.5 does not work anymore since Plaxis 2D Version 9.0. Users should use PlaxFlow Version 1.6, which will be installed as a part of the Plaxis 2D suite, to have the coupling restored.
• When using the PlaxFlow integration with PLAXIS 2D, Plaxis recommends the combination of PLAXIS 2D Version 9.02 and PlaxFlow 1.6, or later versions when they are released.
• Plaxis 3D Tunnel 2 compatibility: Due to a difference in the handling of files, projects saved in Plaxis 2D Version 9.0 or later will not be read in Plaxis 3D Tunnel Version 2.4.

This update can be used for PLAXIS 2D Version 8 only.
All changes made in previous Update Packs have been incorporated in Plaxis 2D Version 8.6.
This Update is a self-extracting and installing package. After downloading, please run it and follow instructions.

CRITICAL BUGFIX

For Plaxis Version 8.6, the following critical issues have been solved:

• In the calculation kernel of Plaxis Version 8.5, the soft soil creep model showed unrealistic stress relaxation at the start of a phase. This bug has been solved for Version 8.6.

New features

PLAXIS Version 8.6 contains new features compared to PLAXIS Version 8.5:

• Apart from the English, Japanese and Chinese language packs, Version 8.6 introduces the Indonesian language pack. For resetting the language, the user must run the PLAXIS Version 8.6 Input program and press CTRL+SHIFT+ALT+R. After restarting PLAXIS Version 8, the user may choose the desired language.

Bug Fixes

In PLAXIS Version 8.6, the following major improvements have been made:

PLAXIS Calculations and Staged Construction

• Sometimes, for unknown reasons, the calculation phase list contained multiple initial phases or invalid calculation types. This will no longer lead to bad program behaviour.

Known issues

• During groundwaterflow calculations, some combinations of well’s discharge values, soil permeabilities and model sizes will scale the well’s discharge values. After a calculation, these values are not scaled back. This could lead to strange discharge values in the results. The location of the phreatic line could also be incorrect. Users should check for valid flow results after a groundwater calculation

Project compatibility

• Due to a difference in the handling of files since Plaxis Version 8.2 with Update Pack 6, files made with this version, or newer, cannot be read in Plaxis Version 8.2 with Update Pack 4 or older.
• Also, the interaction with PlaxFlow Version 1.1 does not work anymore since Plaxis Version 8.2 with Update Pack 6. Users should install PlaxFlow Version 1.5 to have the integration restored.
• Projects with wells defined in Plaxis Version 8.5 or later can cause errors when read in earlier versions.
• Projects with wells in transient groundwater conditions from Plaxis Version 8.4 or older require a new mesh and new groundwater flow calculations to compute the correct discharge values. Steady state groundwater flow calculations with wells that are calculated in Version 8 do not require a new mesh.
• Plaxis Version 8.6 is able to read projects created with earlier versions of Plaxis Version 8, and Plaxis Version 7.
• When using the PlaxFlow integration with PLAXIS Version 8, Plaxis recommends the combination of PLAXIS Version 8.6 and PlaxFlow 1.5, or later versions when they are released.

Plaxis 3D Tunnel 2 compatibility

Due to a difference in the handling of files, projects saved in Plaxis Version 8.2 with Update Pack 6 or later (this includes V8.6) will not be read correctly in Plaxis 3D Tunnel Version 2.0 (includinge Update Pack 1 and 2). Users are advised to import the 2D-geometries in Plaxis 3D Tunnel 2.4 or later.

This update can be used for PLAXIS V8.1 and V8.2 only.
All changes made in previous Update Packs have been incorporated in Update Pack 8.
This Update Pack is a self-extracting and installing package. After downloading, please run it and follow instructions.

Note: When installed over Update Pack 1 or 2 this Update Pack will increase the version number from Plaxis 8.1 to Plaxis 8.2 due to added functionality.

Features

This update pack offers the following additional functionality compared to Plaxis Version 8 Update Pack 4:

• Steady state groundwater flow for axisymmetric problems has been reintroduced.
• The Modified Cam Clay model has been added to the available soil models.
• A set of revised manuals is included.
• Alternative examples (lesson 4 and lesson 6) using the Hardening Soil model are included.

The following major issues have been solved in PLAXIS Version 8.2 Update Pack 8:

• User defined soil models with names other than UsrMod.dll can be used again
• Output tables of effective and total stresses show the calculated stress values again
• When different soil datasets have the exact same color, changing one dataset’s color will no longer change the other data set’s color
• Hardlock drivers of October 2005 will be installed during the setup of Plaxis Version 8.2 Update Pack 8, if needed
• Additionally, some minor issues have been solved too.

The following major issues have been solved in PLAXIS Version 8.2 Update Pack 7:

• Plaxis users on East Asian Windows systems experienced problems with calculating projects when using non-English characters for project names and saving their projects in folders that contain non-English characters. This issue has been solved for this update pack
• Improved reliability of the 'pack project' option
• Zooming sometimes gave the wrong part of the plot in Output

The following major issues have been solved in PLAXIS Version 8.2 Update Pack 6:

• Improvement of the visualization of pore pressures in the output program.
• Display of pore pressures and groundwater heads with non-porous soil clusters have been improved.
• Creating cross sections have been improved.
• Shaded plots of nearly constant quantities were not always drawn.
• The total stresses table was not visible.

Important

Due to a difference in the handling of files since Plaxis Version 8.2 Update Pack 6 (this includes Update Pack 6, 7 and 8), files made with one of this version cannot be read in earlier versions of Plaxis Version 8. Plaxis Version 8.2 can read projects created with earlier versions,

Plax Flow integration

Due to a difference in the handling of files since Plaxis Version 8.2 Update Pack 6 (this includes Update Pack 6, 7 and 8), Plaxis Version 8.2 and Plax Flow do not interact. Users of Plax Flow are advised NOT to install this Plaxis Version 8 Update Pack now. These users are advised to wait for the release of an update pack for Plax Flow.

Since the release of PLAXIS 2D V9, the Plaxis deformations program and the transient groundwater flow program (PlaxFlow) are only available as a software suite installation.

Important: for the coupling with the deformations program, PlaxFlow Version 1.6 can only be used in combination with PLAXIS 2D V9. When using PLAXIS 2D V8, please use PlaxFlow Version 1.5.

In order to obtain the latest version of PlaxFlow, please install the latest version of PLAXIS 2D V9. Please see above software update for PLAXIS 2D V9.

Please note that the license system has been changed since PlaxFlow V1.6. PlaxFlow V1.5 and earlier used the Hardlock key (blue hardlock) system, just like PLAXIS 2D V8. PLAXIS 2D V9 and later, and PlaxFlow V1.6 and later use the CodeMeter dongle (silver dongle) system.

This update can be used for PlaxFlow Version 1 and all its Update Packs. All changes made in previous Update Packs have been incorporated in PlaxFlow Version 1.5.

This Update Pack is a self-extracting and installing package. After downloading, please run it and follow instructions.

Bug fixes

In PlaxFlow Version 1.5, the following major improvements have been made:

Version 8 integration

• With the release of Plaxis Version 8.5, the coupled calculation of transient groundwater flow and deformation analyses has been restored:
• Problems occuring when phases in Version 8 were inserted or deleted are now solved. When phases containing transient water condition info were deleted, this transient groundwater flow information was not deleted from the project. This caused errors when loading phases of the same project in PlaxFlow. Similiar problems occurred when inserting phases.
• Discharge values of wells were not correctly read from Version 8 into PlaxFlow and vice versa.

Known issue

There are some problems with the discharge of wells in combination with very small numerical values of the permeability of the soil (k < 10^-3). It is therefore recommended to use ?day? as unit for time instead of ?s? (sec) as this will increase the numerical value of the permeability.

Project compatibility

• Due to a difference in the handling of files in PlaxFlow Version 1.5, files made with PlaxFlow Version 1.5 cannot be read in earlier versions of PlaxFlow. However, PlaxFlow Version 1.5 can read all projects made in earlier versions.
• Compared to PlaxFlow Version 1.1 Update Pack 3 there have been some modifications in the material parameters, the default values for the calculation settings and the specifications of the time-dependent boundary conditions by tables. Therefore, it is advisable to check the materials in the material database and the settings of each calculation phase, especially when a new mesh is created immediately after opening the project. This is also recommended when a project in Version 8 has been defined by a transient groundwater flow in PlaxFlow Version 1.1 Update Pack 3.
• Due to a difference in the handling of files since Plaxis Version 8.2 Update Pack 6 (this includes Version 8.2 Update Pack 6, 7 and 8, Version 8.3, Version 8.4 and Version 8.5), these versions of Plaxis Version 8 do not interact with PlaxFlow Version 1.1. Users should install PlaxFlow Version 1.5 to have the integration restored. When using the PlaxFlow integration with PLAXIS Version 8, Plaxis recommends the combination of PLAXIS Version 8.5 and PlaxFlow 1.5, or later versions when they are released.
• Projects with wells in transient groundwater conditions from Plaxis Version 8.4 or older require a new mesh and new groundwater flow calculations to compute the correct discharge values.

This update can be used for PLAXIS 3D Foundation Version 2 only.
All changes made in previous Updates have been incorporated in PLAXIS 3D Foundation Version 2.2
This Update Pack is a self-extracting and installing package. After downloading, please run it and follow instructions.

New Features

New features in Plaxis 3D Foundation Version 2.2

• A grid designer for direct input of pile groups, point loads and other point-related input
• Curved (isoparametric) volume elements and curved plate elements based on Mindlin's theory.

For more details, please read the //3D Foundation Version 2.2 Manual Addendum//

New features in Plaxis 3D Foundation Version 2.1

• Embedded piles: embedded beam elements with predefined bearing capacity. This embedded pile can be placed arbitrary in the geometry
• Ground anchors: A Combination of embedded beam elements and node-to-node anchors
• The use of the Soil Tests application: Easy simulation of soil lab tests for Plaxis Soil models (V.I.Plaxis service program)
• A new Soil Model: Hardening Soil with Small Strain Stiffness models (V.I.Plaxis service program)
• Vertical mesh refinement
• User defined boundary conditions for consolidation analysis

Another great improvement for the Plaxis 3D Foundation program is the introduction of multi-select and grouping. With these groups, it is possible to change the materials and to switch these items on or off per group.

Calculation kernel

The calculation kernel in Plaxis 3D Foundation Version 2.1 now supports:

• Combination of staged construction with consolidation analysis
• Phi/c reduction for safety analysis
• User defined soil models

Post-processing (output and curves)

With Plaxis 3D Foundation 2.1 the Post Processing program has been completely renewed:

• It now includes both the “Curves” program. This means that it is no longer necessary to save in order to generate curves and that the curve points do not have to be selected before the calculation.
• This new post processing program uses OpenGL for enhanced and faster 3D result display: navigation in the 3D model and its rotation has been improved tremendously.
• A new item for the Plaxis 3D products is the creation of animations of the 3D results.

Manuals

Since the release of Plaxis 3D Foundation 2.1, the manuals have been completely revised. These manuals are available in a digital format (PDF) on the official Plaxis 3D Foundation 2.1 CDROM or on the Plaxis website.

V.I.Plaxis service program

With Plaxis 3D Foundation Version 2, the Plaxis V.I. service program has also been introduced, just like the Plaxis 2D Version 8 program. With this V.I.Plaxis service program, users have now access to:

• The Soil Tests application: Easy simulation of soil lab tests for Plaxis Soil models, and
• A new Soil Model: Hardening Soil with Small Strain Stiffness

New hardware key

3DFoundation version 2.1 uses a new hardware key: the WIBU/CodeMeter key. Users with an existing license and the old hardlock, who want to use the new version, can contact the Plaxis sales department in order to obtain the new key.

Fixes in Plaxis 3D Foundation Version 2.2

Pre-processing

• When changing the water weight after already defining boreholes, the water weight was not changed in the borehole dialogues to calculate the hydrostatic water pressures. The program calculated the water pressures correctly in the final results. In the latest version, the water weight is now also adjusted in the borehole dialogues for the hydrostatic water pressure values.
• In the previous version, groups were not stored. In Version 2.2, when loading a 3D Foundation project, the previously used groups are also loaded.
  The consolidation boundaries were not always saved correctly after changing these boundary conditions. In Version 2.2, the boundaries are stored correctly after each change.
• Units for permeability were always shown with the standard units, not with the project units, although the calculation kernel calculated it with the project units. In Version 2.2, the correct (project) units are shown.
• Storing the K0, OCR and POP values sometimes got mixed up. In Version 2.2 the K0 values can now be set in the drawing mode boreholes, and in the parameters tab of the initial phase when K0-procedure is selected.
• OCR and POP values could not be set for the HS small model. In Version 2.2 this can be done.
• Beam data sets: when using a value for I23, larger than I2 or I3, the calculation kernel reported that there were 'negative pivots'. In Version 2.2, I23 is limited to the maximum of I2 and I3. However, care must be taken with I23 > 0.
• The non-linear diagrams for beams, walls and floors where not copied correctly from the global database. Since Version 2.2, these datasets are copied correctly to the project database and vice versa.
• When directly using the layer dependent skin resistance for the embedded pile, the calculation kernel could show a "severe divergence" error message. This severe divergence does not occur any more when using the embedded pile with a layer dependent skin resistance.
• Due to the internal accuracy of embedded pile point locations, the embedded pile could not be added to a work plane with more than four digits. In previous versions, when one tries to add an embedded pile to a work plane at  e.g. y = 190.84 m, the pile was added to workplane y = 190.80 m. This lead to problems if this work plane did not exist. In Version 2.2, the pile is added to the correct workplane.
• When trying to close the program while zoomed in, the program seemed to crash. In Version 2.2, the program closes now without problems.
• Selecting the "Set as default" did not work for gravity acceleration and water density. Since Version 2.2, these values can also be stored as default.
• Water density and gravity acceleration were restricted, which would lead to problems when using unit combinations of e.g. kN and mm. In Version 2.2, these restrictions have been removed.
• In Version 2.1, the text reference in the warning text for phi/c reduction just below the calculation type selection box does not always refer to the correct phase title. The actual calculation order using during the calculation was correct though. In Version 2.2, this reference for the phase title in the phi/c reduction warning text has been corrected.
• Borehole settings were not always copied correctly to the next phase. In Version 2.2, these settings are now copied correctly when adding a new phase and when using the 'Reset staged construction' option.
• Sometimes, after loading a project, the program gave a message that some previously calculated step does not exist. In Version 2.2, the correct data is copied when opening (partly) calculated projects, if these are saved correctly.

SoilTest

A revised soiltest application is included in which:
the triaxial test is improved: users can now perform:

• a drained or an undrained test,
• compression or extension test
• specify starting conditions: isotropic or K0

for advanced soil models:

• isotropic preconsolidation pressure is now an absolute value
• the initial mobilised relative shear strength is now an input parameter for the Hardening Soil Model and the Hardening Soil Model with Small Strain Stiffness

Mesh Generation

• Internal tolerances during the triangulated mesh generation could lead to strange jumps and dents in the generated surfaces. In Version 2.2, the internal tolerance has been redesigned in order to fix this. This also fixes the sometimes strange layer configurations near crossings of workplanes and soil layer boundaries.
• Cluster refinement with the triangulation option did not always work as expected. When refining clusters in 3D Foundation Version 2.2, the entire cluster will be refined, even when triangulation lines are added between the boreholes.
• The mesh generation showed a memory leak for some cases with grouped elements and inclined soil layers. When the program tried to allocate memory and exceeded the maximum available memory, the mesh generation failed. In Version 2.2, this memory leak has been fixed.
• When using a lot of volume piles, sometimes the results did not show all the internal volume pile results for all volume piles. This was due to an internal numbering error. In Version 2.2, this internal numbering is corrected and all (internal) volume pile results are shown in the Output program.
• When a project contained a lot of points due to volume piles, the number of points exceeded the maximum number of points allowed in the mesh generation process (5000). In Version 2.2, all points will be filtered and renumbered. This will prevent that the number of points will exceed the maximum allowed points under normal circumstances.

Calculation kernel

• When loading volume pile with lateral loads, the pile bearing capacity was over-estimated. In Version 2.2 this has been improved by introducing curved Finite Elements and plate elements based on Mindlin's theory. For more details, please read the Version 2.2 Manuals Addendum. Please note that the bearing capacity can still be over-estimated.
• When a point load is acting on the same point as a deactivated embedded pile, the point load was still transferred to this inactive embedded pile. In Versions 2.2, the point load will be transferred to the active embedded pile, or to the surrounding soil or floor when the embedded pile is switched off.

Post-processing (output and curves)

• In Version 2.2, the state parameter plots show their values. In Version 2.1 the plots did not show any values; the tables contained the correct values though.
• The Hardening Soil Model with Small Strain Stiffness (HS small) shows the p_eq and OCR values.

The logarithmic scale along axes of the curves are shown correctly.

• Regeneration of the 3D-mesh will now reset the staged construction settings.
• Newly inserted planes in the 3D mesh-generation window will now start with valid z-values.
• When switching to geometry input from initial conditions and back the program will not ask for regeneration of mesh.
• The drawing of the general phreatic level is restricted to one.

PLAXIS Calculations

• The efficiency and memory usage of the ground water flow calculation has been improved.
• The calculation accuracy for an elasto-plastic plate when using ‘total multipliers’ has been relaxed to allow for faster convergence.
• The irrelevant parameters displayed in the window of groundwater flow-calculation have been removed.

PLAXIS Post processing (Output and curves)

• Several improvements have been made in the display of groundwater flow-calculation results.

Known issues

• Due to a difference in the handling of files since Plaxis 3D Tunnel Version 2.4, files made with this version, or newer, cannot be read in Plaxis 3D Tunnel 2 (including Update Pack 1 and 2) or older.
• User defined water conditions in the front and rear plane will be overwritten by the general option ‘closed plane (groundwater flow/consolidation)’.
• In output it is not possible to view the state variables of the Hardening Soil model and the Soft Soil (Creep) model.
