New in PLAXIS 2D 2025.1.2
Release: February 2026
PLAXIS 2D 2025.1.2 (25.1.2.76) contains the following improvements and updates compared to PLAXIS 2D 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, especially for 15-noded triangular elements.
- Some coupled, flow and thermal 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.
- 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 note: 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 2D 2025.1.
Other changes and improvements
- 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.
- SOLVED Known Issue: Resolved error 604 concerning a PLAXIS 2D Dynamics calculation that included horizontal interface elements at the model’s top boundary (YMax) while free-field conditions were applied to the model boundaries.
- Performance of the checkgeometry command has been improved returning adjacent geometry pairs faster.
- 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.
- Import PLAXIS LE (Technology preview) feature removed from the PLAXIS 2D software.
- 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.
- Minor improvements in the plotting of curves in the calculation progress window.
- Support for Academic licences.
- Support for Student licences with watermarking on results.
