Optimization Constraints
Optimization constraint entities define and store constraints on model responses for optimization problems.
Optimization constraints do not have a display state in the モデリングウィンドウ.
Nastran Cards
| Card | Description |
|---|---|
| DCONADD | Defines the design constraints for a subcase as a union of
DCONSTR entries. 注: Collects constraints
|
| DCONSTR | Defines design constraints. 注: Constraint to define lower and upper
bounds.
|
| DESGLB | Selects the design constraints to be applied at the global level in a design
optimization task. 注: Global constraint; belongs in the subcase
section.
|
| DESSUB | Selects the design constraints to be used in a design optimization task for
the current subcase. 注: Constraint dependent on the load step; Belongs in the
subcase section.

OptiStruct Cards
| Card | Description |
|---|---|
| DCONADD | Creates a combination of several
DCONSTR sets that can be referenced by a subcase. 注: Bulk Data Entry
|
| DCONSTR | Defines design constraint upper and lower bounds where
response is defined by DRESP1, DRESP2, and
DRESP3 cards. 注: Bulk Data Entry
|
| DESGLB | Used before the first subcase statement, to select a
constraint set that is not subcase dependent. 注: I/O Options and Subcase Information Entry
|
| DESSUB | Used within a subcase definition, to select a
constraint set that is subcase dependent. 注: Subcase Information Entry

Radioss Cards
| Card | Description |
|---|---|
| DCOMP | Defines manufacturing constraints for composite sizing optimization. |
| DCONSTR | Defines constrains a design response by specifying its lower and upper bounds. |
