Objective and Response Constraint Capability Map
The options for the Objective and Response Constraint object depend upon the analysis you are optimizing, the response constraint you want to specify, and the optimization method you are using. Review the following table to see which Objective and Response Constraint objects are available for each method, noting the following:
Constraint/Objective (C/O): Supported as Response Constraint and Objective.
C: Supported as a Response Constraint only.
O: Supported as a Objective only.

[a] This response will be deprecated in a future release. Ansys recommends that you use a User Defined Criterion response instead as it is more versatile.
[b] The Structural Optimization analysis only supports an upstream standalone MSUP Harmonic Response analysis.
[c] The application ignores Condensed Part objects included in the model when computing compliance.
[d] To specify a nonlinear analysis, set Large Deflection property to On in the Details of the Solver Controls category of the Analysis Settings.
