Field |
Contents |
ID |
Relationship identification number. ID must be unique with respect to other DVMREL1 cards. No default (Integer > 0) |
TYPE |
Material type to be related (MAT1, MAT2, MAT4, MAT5, MAT8, MAT9, or MAT9ORT). No default (Character) |
MID |
Material identification number. No default (Integer > 0) |
MPNAME/FID |
Material property name, such as "E" or “RHO" (as in the documentation of the material bulk data entries), or field number on a material bulk data entry. No default (Character or Integer > 0) |
C0 |
Constant in relationship equation. Default = 0.0 (Real) |
DVIDi |
DESVAR ID. No default (Integer > 0) |
COEFi |
Coefficient in relationship equation. Default = 1.0 (Real) |
