|
| DDVID | Dependent Design Variable
identification number. (Integer > 0) |
|
| C0 | Constant. Default = 0.0 (Real) |
|
| CMULT | Constant
multiplier. Default = 1.0 (Real) |

| Ci | Coefficient multiplier for
IDVi. (Real) |
Comments
- DLINK defines the
relationship.
(1) DDVID=C0+CMULT∑iCi*IDViThis capability allows physical and non-physical design variables to be related such as shell thickness and interpolating functions.
- CMULT and Ci can be used together to provide a simple means of scaling.
- This card is represented as an optimization design variable link in HyperMesh.
