DVMREL1

Bulk Data Entry Linearly relates a design variable to an analysis model material property using the equation: ${MP}_{i} = C_{0} + \sum_{i} {COEF}_{i} \cdot {DVID}_{i}$

Format


(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
DVMREL1	`ID`	`TYPE`	`MID`	`MPNAME`/ `FID`			`C0`
	`DVID1`	`COEF1`	`DVID2`	`COEF2`	etc.

Example 1

To relate the Damping Coefficient value on a MAT1 card (field 9) to Design Variable 5.


(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
DVMREL1	17	MAT1	22	9			0.0
	5	1.0

Example 2

This example is the same as Example 1, except that it defines MPNAME in place of FID.


(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
DVMREL1	17	MAT1	22	GE			0.0
	5	1.0

Definitions


Field	Contents	SI Unit Example
`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 MAT9OR). 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)
