FGRAD
FGRAD, MATID,
Option, PERT_SIZE
Directs the solver to include the effects of field-dependent gradients in the
solution.
Valid Products:
Pro | Premium | Enterprise | PrepPost | Solver | AS add-on
MATIDMaterial reference identification number.
OptionField dependent gradient option to define:
STTE
—
Gradient of structural components with respect to temperature.
PERT_SIZEPerturbation size for numerical derivatives (defaults to 1e-8).
Notes
The FGRAD command specifies the consideration of field-dependent gradients in coupled-field analyses.
When the derivatives are calculated numerically, the perturbation size is used.
