Control Field

Represent a spatial design variable rather than a single scalar parameter.

Where to find it

Definitions → Variables

How to use it

Select the entities and bounds needed by the optimization problem before using the field in an objective or material expression.

Settings and initial values

Result

Valid expressions can be selected by later model features.

Troubleshooting

A finer control field increases the design problem size; first check that the objective supports the chosen design variable.
