Description

DDVOPT

< 1, 2, or 3 >

Default = 1

Discrete Design Variable Option.

Use 1 for full discrete design optimization.

Use 2 for two-phased approach, a continuous optimization phase followed by a discrete optimization phase (starting from the continuous optimum).

Use 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.
