DOPTPRM, DESMAX or MAXITER

Bulk Data Entry Defines the maximum number of design iterations.

Definitions

Parameter Values Description
DESMAX

or

MAXITER

Integer ≥ 0

Default = 30

Default = 80 if manufacturing constraint is defined.

Default = 100 for Level Set Topology Optimization.

Default = 200 if stress norm response is defined.

Maximum number of design iterations.

Comments

  1. If optimization is restarted, this parameter implies the number of design iterations after restart. Therefore, if 30 iterations are done prior to restart and DESMAX is now set to 50, then the limit is 50 iterations after restarting optimization.
  2. If an OptiStruct optimization model has DOPTPRM, DESMAX, 0, the number of license units checked out is the same as the checkout for an OptiStruct analysis job.
