Structural Optimization Variables

Structural optimization output variables are requested by the Optimization module during each design cycle.

This page discusses:

The output variables listed below are available in Abaqus/Standard.

Topology Optimization

The following variable is output automatically during topology optimization (see Topology Optimization).

MAT_PROP_NORMALIZED
Field: automatic  History: no  .fil: no  .dat: no
