PLAXIS 3D CE V21.00.01 Release notes

New in PLAXIS 3D CONNECT Edition V21 Service Release 1

Release: February 2021

PLAXIS 3D CONNECT Edition V21 (21.00.01.07) contains the following improvements and updates compared to PLAXIS 3D CONNECT Edition V20 Update 4:

New features

PLAXIS product licenses
Replaced legacy PLAXIS product options and modules by a tier-based licensing system consisting of three tiers: PLAXIS 3D (a new license type), PLAXIS 3D Advanced (similar to legacy PLAXIS 3D), and PLAXIS 3D Ultimate (similar to the full legacy PLAXIS 3D Suite).
New constitutive model: NorSand
Added the NorSand model as a User Defined Soil Model. The model is typically used to simulate static liquefaction of loose silts, the mechanism understood to be the cause of several recent tailings dam failures.
New constitutive model: Fluid
Added a Fluid model as User Defined Soil Model. The model can be used to model water bodies as continuum elements with an appropriate constitutive model.
Tunnel import workflow improvements
Improved workflow for importing tunnel cross-sections and tunnel trajectory into the Tunnel Designer. New functionality includes selecting, snapping and intersecting tunnel segments and subsections during import. This makes importing Tunnel cross section CAD files much easier to handle and ensures proper geometric connectivity.
Calculation Kernel convergence log
Added a tool for accessing calculation convergence log files during and after calculations to gain more insight into the convergence process. This will ease pinpointing possible causes of non-convergence.
Updated Python environments
Updated Python environments to remove security vulnerabilities on some of the included packages.
Python distribution folders are now updated and default location changed to C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V1 Update 1\

Fixed issues

The following Known issues have been resolved:

Many other issues have been fixed, including:

  • [501119] making the echo command for volumes more consistent after several file loading
  • [455620] Embedded beam Layer dependent skin-friction now uses correct strength parameters when using UBC Sand to compute shaft resistance.
  • [442603] In rare cases, the set command could lead to a crash in Staged Construction mode
  • [441761] Fixed an issue when using the commands runner for calculating projects with long command lists
  • [439676] In some cases, loads display in Output lead to very high memory usage. This is now solved.
  • [438739] PLAXIS 3D crashed when adding more than 255 material datasets. This is now resolved
  • [421272] Void ratio value update based on volume strain is now improved
  • [393075] Fixed an issue in amplification spectra determination to use the proper Fourier data to get correct amplification spectra curves
  • [379743] Inaccuracy in embedded beam results are now also included in first step determination, leading to faster convergence in cases with high plasticity
  • [379528] Creating cross-sections for plates could lead to a crash. This is now solved.
