    PLAXIS 2D CE V21.00.01 Release notes

    New in PLAXIS 2D CONNECT Edition V21 Service Release 1

    Release: February 021


    PLAXIS 2D CONNECT Edition V21 (21.00.01.07) contains the following improvements and updates compared to PLAXIS 2D 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 2D (a new license type), PLAXIS 2D Advanced (similar to legacy PLAXIS 2D), and PLAXIS 2D Ultimate (similar to the full legacy PLAXIS 2D 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: PM4Silt
    Added the PM4Silt model as User Defined Soil Model. The model is intended for earthquake engineering applications and liquefaction analysis on low-plasticity silts and clays.
    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 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\
    Technology Preview: PLAXIS LE Model importer
    Some bugfixes and stability improvements have been implemented.
    Renamed SOILVISION model importer to PLAXIS LE model importer
    Added functionality to import PLAXIS LE, SVSLOPE, and SVSOLID material definitions and their supported parameters to an equivalent PLAXIS constitutive soil model.

    Fixed issues

    The following Known issue has been resolved:

    • Solved: [540768] PLAXIS CONNECT Edition V21.00.00 calculation does not start due to a license issue
    • Solved: [447463] PLAXIS 2D meshing stops with error Ordinal 747 not located

    Many other issues have been fixed, including:

    • [501119] making the echo command for volumes more consistent after several file loading
    • [457052] Grid settings for drawing tools did not show unit aware length units. This is now fixed.
    • [457037] Intersection of overlapping polygons and lines, leading to small polygons, is now improved.
    • [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
    • [433620] Fixed an issue with large ratios of permeability for steady state groundwater flow calculations.
    • [421272] Void ratio value update based on volume strain is now improved
    • [393075] Fixed an issue in amflication spectra determination to use the proper Fourier data to get correct amflication spectra curves
    • [379568] Expanded documentation on movedisconnected command
