Supported types of optimization for various analysis sequences are
outlined.
OptiStruct supports topology, shape, size, free-shape,
free-size and topography optimization for almost all analysis sequences. The
supported responses for each analysis type are listed in the subsequent tables.
Each optimization type is associated to a specific table which outlines supported
responses types.
