The software can automatically select the most robust solver for Nonlinear studies.
In the Nonlinear - Static dialog box, under Solver, select Automatic Solver Selection.
The program selects the most robust between two solvers depending on the size of the model and available RAM:
- Intel Direct Sparse solver. For small and medium size models with slim geometry. The Intel Direct Sparse solver requires more RAM than the FFEPlus Iterative Solver.
- FFEPlus Iterative Solver. For medium size models with bulky geometry, and large models.
