Design variable entities are used to define and store design variables for optimization problems. Design variables are shown under the DesignVariable folder within the Model browser. The Optimization View can be utilized to create, edit, and delete optimization problems.
Design variables do not have a display state.
Design variables have an active and export state. The active state of a design variable controls the listing of the design variable in the Model browser and any of its views. If a design variable entity is active, then it is listed in the Model browser and any of its views. If a design variable entity is inactive, then it is not listed in the Model browser or any of its views.
The export state of a design variable entity controls whether or not that design variable is exported when the custom export option is utilized. The all export option is not affected by the export state of a design variable. The active and export states of design variable entities can be controlled using the Entity State browser.
The data names associated with 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 design variables:
Solver Card Support for 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. The optimization panels are available from the Optimization menu when the OptiStruct user profile is loaded.

Some of the functionality of the optimization capability is general. This includes the equation utility, delete, rename, renumber, and reorder. To set up an optimization problem, responses, an objective function and constraints need to be defined. Further, design variables need to be defined. The optimization panels have separate Delete, Rename, Renumber, and Reorder panels to manipulate optimization entries. These can be reached through the Optimization panel.
