New in PLAXIS 2D CONNECT Edition V21
PLAXIS product licences
Replaced legacy PLAXIS product options and modules by a tier based licencing system consisting of three tiers: PLAXIS 2D (a new licence 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.
