Comments
- If the FID field of DVCREL1/2 is set to T, then the averaged nodal thickness is used as a design parameter for optimization. The CQUAD4, CTRIA3, CQUAD8, CTRIA6 elements are supported. There is no support for Nastran Item Codes for this parameter. Even though the averaged nodal thickness value is optimized, the actual nodal thicknesses are updated (while preserving the element aspect ratio). This is also written out into the .prop file.
