PLAXIS 3D Readme

New in PLAXIS 3D CONNECT Edition V22

New material objects data structure

Existing materials database has been replaced with new material objects data structure, providing better command-line support and richer editing experience for material models.

Support for manual local axes in polycurves

Added support for manual local axes in polycurves.

Improved unit system

Improved handling of units through a uniform unit system, maintaining consistent physical dimensions of the PLAXIS model following changes to the project units.

Improved handling of project units during import

Improved handling of project units for imported DXF and STEP files.

Support for writing custom project during export

Added support for writing custom project units during export to DXF and STEP files.

Upgraded Python environments

Upgraded Python environments to Python 3.8.x with the purpose of fixing security vulnerabilities in included OpenSSL library.

Technology preview: Support for triangulated surfaces

Added support for triangulated surfaces, through STL and OBJ file formats.

Technology preview: Soil structure interaction through super element

Added support for importing structures and load cases by means of a super-element approach, applied at the interface between the soil and structure, and calculating the interaction based on the structure's contribution and true soil response. Resulting forces and displacements at the interface between the soil and structure are stored or exported, and can be used for the determination of spring stiffnesses in subsequent structural analysis models.
