DOPTPRM, DDVOPT

Bulk Data Entry Control options for discrete design optimization.

Definitions

Parameter	Values	Description
DDVOPT	<1, 2, or 3>	Discrete Design Variable option. 1 (Default) For full discrete design optimization. 2 For two-phased approach, a continuous optimization phase followed by a discrete optimization phase (starting from the continuous optimum). 3 For a continuous optimization regardless of DDVAL definitions. The bounds will be affected by DDVAL if DDVAL bounds are more restrictive than those defined on DESVAR.
