DVMREL2

Bulk Data Entry Relates design variables to an analysis model material property using a relationship defined by a DEQATN card. The equation inputs come from the referenced DESVAR values and constants defined on a DTABLE card.

Example 1

To relate the Damping Coefficient value on a MAT1 card (field 9) to some user-defined relationship of design variables 5 and 6 and the table entry GE0.

Example 2

This example is the same as , except that it defines MPNAME in place of FID.
