/DVPREL2
Optimization Keyword Relates a design variable to an analysis model property using a relationship defined by a /DEQATN card.
The equation inputs come from the referenced /DESVAR values and the constants defined on the /DTABLE card.

identifier to be related with design variable. Depending on
various property types (prop_typ), the
available options are different. 1 (Integer > 0) |
|
EQID | /DEQATN identifier that defines the
response relationship. (Integer > 0 or blank) |
|
VARTYPE# | Variable type.
(Integer > 0 or blank) |

variables defined in VARTYPE#.. When VARTYPE is DESVAR, or DTABLE, this list of IDs reference entities of the defined VARTYPE. |
Comments
- The specific property
field ID's that are related to the design variables are listed based on the
following property types:prop_type = 1 (/PROP/SHELL):
- prop_fid
- 1
- Thickness
prop_type = 2 (/PROP/TRUSS):- prop_fid
- 1
- Area
prop_type = 3 (/PROP/BEAM):- prop_fid
- 1
- Area
- 2
- Iyy
- 3
- Izz
- 4
- Ixx
prop_type = 11 (/PROP/SH_SANDW):- prop_fid
- > 0
- Ply Thickness
- < 0
- Ply Orientation Angle
prop_type = 18 (/PROP/INT_BEAM):- prop_fid
- 1
- First size of the predefined section L1
- 2
- Second size of the predefined section L2
- This card is represented as an optimization design variable in HyperMesh and HyperCrash.
