Optimization Responses
Optimization response entities define and store model responses for optimization problems.
Optimization responses do not have a display state in the modeling window.
Nastran Cards
| Card | Description |
|---|---|
| DRESP1 | Defines a set of structural responses that is used in the design either as
constraints or as an objective. Note: Generic response
|
| DRESP2 | Defines equation responses that are used in the design, either as constraints
or as an objective. Note: Function response
|
OptiStruct Cards
| Card | Description |
|---|---|
| DRESP1 | A response or a set of responses that are the result of a
design analysis iteration. These responses can be used as a design objective or as
design constraints. Note: Bulk Data Entry
|
| DRESP2 | When a desired response is not directly available from
OptiStruct, it may be calculated using
DRESP2. This response can be a functional combination of any
set of responses resulting from the design analysis iteration. Responses defined in
this manner can be used as design objectives or constraints. The
DRESP2 card identifies the equation to use for the response
relationship and the input values to evaluate the response function. Note: Bulk Data Entry
|
| DRESP3 | When a desired response is not available from OptiStruct, either directly or via equations, it may be
calculated through external user-supplied functions implemented in shared/dynamic
libraries or external files. The DRESP3 card identifies the
external function to be called and defines the parameters to be transferred to that
function. Note: Bulk Data Entry
|
| DSYSID | Defines responses and their target values for a system
identification problem. Note: Bulk Data Entry
|
| MODEWEIGHT | Defines a multiplier for computed eigenvalues that
are to be used in the calculation of the "weighted reciprocal eigenvalue" and
"combined compliance index" optimization responses. Note: Subcase Information Entry
|
| PSD STRAIN | |
| PSD STRESS | |
| RMS STRAIN | |
| RMS STRESS | |
| WEIGHT | Defines a multiplier for computed eigenvalues that
are to be used in the calculation of the "weighted reciprocal eigenvalue" and
"combined compliance index" optimization responses. Note: Subcase Information Entry
|
Radioss Cards
| Card | Description |
|---|---|
| DRESSP1 | Defines a response (mass, displacement, stress, velocity, and so on) or a set of responses. |
| DRESP2 | Design Response via Equations for Design Optimization. |
