Create Rules
The boundary conditions for the design study will be assigned automatically using the rules created in this step.
In this example, the boundary conditions could have easily been applied with the Template. However, for models that contain many instances of the same condition (such as electronics studies), a rule can be much more efficient because it automates application of the setting based the rule basis.
Expand the Launch panel, and select Rules.
