# Release Update

### DANTE 6.3x updates

* FEA with Ansys solver, distributed cpus were implemented (intel mpi installation (impi.dll) is required, which comes from Ansys installation package).
* FEA with Ansys solver, 2D (axisymmetric) model was validated. Ansys version requires 2025R2 or later.
* FEA with Ansys solver, nitriding model for nitrogen profile mapping to Thermal/Stress model is updated for robustness and tolerate using lower quality meshing.
* FEA with Ansys solver, the carbon profile mapping was improved.
* FEA analysis, the algorithm for carbon partitioning step size and increment size control was improved.
* New help documentation was developed with local help system.
* Pre-processing using Abaqus Plugin, the stress model uses \*odb file from thermal model temperature profiles instead of \*fil file.
* Mat Sim tool, the Ubainite and LBainite label bug was corrected.
* Bug removed, when running models at drive home directory when folder string less than 4 letters.
* Primary creep model was improved. Allows simultaneous primary and secondary creep.
* An improved TRIP model was implemented as option.
* For steel alloys, the thermal properties (specific heat and conductivity) dependency on carbon and nitrogen is implemented.
