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
