February 2025
The release notes for February 2025 are:
General modifications:
- Reduced integrated stabilised elements for unsaturated soils (
uxpx-red-stab) now use full integration for the mass balance of pore water. For more information see footnote (6) in Three-phase porous solid elements - Mohr-Coulomb (1) model
- Improved the performance of the model significantly. A reduction of simulation times by up to a factor of 3 were observed in tests.
- Added the option to exclude the dilatation angle \(\psi\) from strength reduction analysis, see Strength Reduction
- Added the option to include the Poisson's ratio \(\nu\) in the strength reduction analysis, see Strength Reduction
- If the user contact property routine returns zero for the tangential stiffness, the stiffness is determined from the adjacent continuum element as described in the Theory Manual.
Resolved bugs:
- An error message is issued in case element- or node-sets are defined multiple times, which used to cause an internal crash
- Resolved a bug responsible for crashes in certain cases where multiple surfaces were present in one contact pair
- Revolved a bug where the wrong scaling factor for the tangential stiffness of the Coulomb friction model was used
- Corrected input files of Sanisand benchmark simulations
Manuals:
- Added information about the
Flowboundary condition. See the Reference Manual or the Theory Manual. - Added information about optional parameters for the Mohr-Coulomb (1) model.
- Refined documentation of the Strength Reduction in the Theory Manual
- Strength reduction analysis *Reduction now takes four arguments: \(\text{FoS}_0, \Delta \text{FoS}_0, \Delta \text{FoS}_\text{max}, \Delta \text{FoS}_\text{min}\)
