Discrete design variable entities are used to define and store discrete design variables for optimization problems. Discrete design variables are shown under the DiscreteDesignVariable folder within the Model browser. The Optimization View can be utilized to create, edit, and delete optimization problems.
Discrete design variables do not have a display state.
Discrete design variables have an active and export state. The active state of a discrete design variable controls the listing of the discrete design variable in the Model browser and any of its views. If a discrete design variable entity is active, then it is listed in the Model browser and any of its views. If a discrete design variable entity is inactive, then it is not listed in the Model browser or any of its views.
The export state of a discrete design variable entity controls whether or not that discrete design variable is exported when the custom export option is utilized. The all export option is not affected by the export state of a discrete design variable. The active and export states of discrete design variable entities can be controlled using the Entity State browser.
The data names associated with discrete design variables can be found in the data names section of the HyperMesh Reference Guide.
The following panels can be used to create and edit discrete design variables:
Solver Card Support for Discrete Design Variables
An optimization problem is set up by defining responses, which are in turn constrained or set as objectives. Design variables identify the varying quantities in an optimization problem. All of the optimization panels are available from the Optimization menu when the OptiStruct user profile is loaded.
