DVMREL2 – Relates Design Variables to Analysis Model Material Property
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.

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.
|
This example is the same as example 1 (above), except that it defines MPNAME in place of FID.
