New in PLAXIS 3D CONNECT Edition V21

PLAXIS product licences

Replaced legacy PLAXIS product options and modules by a tier based licencing system consisting of three tiers: PLAXIS 3D (a new licence 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.
