GeoStudio | PLAXIS - PLAXIS 3D 2025.1 Release Notes

New in PLAXIS 3D 2025.1.2

Release: February 2026

PLAXIS 3D 2025.1.2 (25.1.2.76) contains the following improvements and updates compared to PLAXIS 3D 2024.3:

New features

New calculation input and results database
The application’s calculation input and calculated results as well as its storage have been redesigned, resulting in many improvements and better consistency of the PLAXIS data. Changes span across calculation input, results calculation, results derivation, curve performance and results availability. Notable changes include:

Improved extrapolation of results from stress points to the nodes.
Some coupled and flow calculation results that are natively computed on the nodes are not extrapolated from the stress points anymore.
Result types that do not exist for certain calculation types or pore pressure calculation combinations etc., are now shown as Not Available instead of zero.
Improved reliability and inspectability of UDSM results including their state parameters when working with multiple UDSM’s.
Some calculation pre-processing done by the kernel regarding connectivity of loads or anchors for phases with different active states of connected soils or structures is moved to the calculation preview and can now be inspected before calculation.
Fixities, prescribed displacements and loads can now be viewed in the mesh preview of the generated mesh.
Drastically increased performance of pre- and post-calc curve generation.
Curve points now include all result types available for specific nodes or stress points, like for example native model and UDSM state parameters.

Compatibility notes: Due to this major change, when opening older projects, they will be converted and saved with a _converted suffix in the 2025.1 format and require remeshing and recalculation. To ease the transition to the new release and not block ongoing projects, side-by-side installation with the previous releases of PLAXIS is supported.
Be aware that earlier versions of PLAXIS will not be able to open files saved in PLAXIS 3D 2025.1.

Other changes and improvements

SOLVED Known Issue: Displacement fixities are now correctly applied automatically to isolated beam elements on model boundaries.
SOLVED Known Issue: Safety calculations for models with beams now calculate, error 602 no longer occurs.
SOLVED Known Issue: Dynamic boundary condition options in PLAXIS projects now show only the allowed options instead of all. PLAXIS 2024.3 projects affected by this issue can be opened with PLAXIS 2025.1 to fix it.
SOLVED Known Issue: Fixed issue with point loads that were incorrectly merged into single point load(s), when they were applied at the top of embedded beams and an interface element existed at the same coordinates.
Safety analysis now correctly disables the reduction of the strength of discontinuities when the property Apply strength reduction is marked inactive.
The safety information table now shows the discontinuities to which strength reduction was applied in a safety analysis.
Performance of the checkgeometry command has been improved returning adjacent geometry pairs faster.
Greatly improved the speed of the pore pressure calculation for models with user imported phreatic level in phase preparation stages, especially in case of a fine FE mesh..
Fixed issue where in some cases importing CAD files failed due to a license error with the DXF importer.
Upgraded Python environment to Python 3.12.11 to keep up with the latest security improvements.
Fixed issue that could stop the calculation with Error code 256, if the model contains plates with the material set option “prevent punching”, marked active.
Minor improvements in the plotting of curves in the calculation progress window.
Support for Academic licences.
Support for Student licences with watermarking on results.
