DOPTPRM, SHAPEOPT

Bulk Data Entry Defines an optional parameter to select an alternative shape optimization algorithm.

Definitions

Parameter Values Description
SHAPEOPT Integer = 1 or 2 This algorithm can be selected when non-moving shapes are encountered in the optimization.
1 (Default)
Default algorithm for shape optimization.
2
Selects the alternate algorithm for shape optimization.

If discrete design variables are present, it is recommended to use this parameter along with design optimization parameter, DDVOPT=2.
