- Support of Radioss solver version 2021
- The new Radioss solver version 2021 is supported along with major keywords updates.
- Elemental time step quality criteria
- The shell elemental time step is now available as meshing quality criteria, which adapts the quality of the mesh with respect to the solver elemental time step value.
