For Thermal Static analysis, select the type of solver:
Auto
Number of Substeps
Number of substeps to be used for this load step (the time step size or frequency increment).
Large Deformation Key
If Ignore is selected, than it will not include large deflection effects in a static or full transient analysis. For the Include option, it will be incorporated in the analysis.
Direct
Enter the Number of Substeps and select the Large Deformation Key option.
ICCG
The incomplete Cholesky Conjugate gradient (ICCG) algorithm is a commonly used iterative method for solving large sparse systems of equations.
Enter the Number of Substeps and select the Large Deformation Key option.
Tolerance
Solver tolerance value (defaults to 1.0e-8).
