Rules are associations between a CAD entity and an Autodesk Simulation CFD setting. You can use them to automatically assign settings to frequently recurring CAD components. Rules are usually applied automatically when the design study is launched.
For example, a line of control modules share many common parts. A naming convention is used in the CAD part library so that each component is named the same in all models. The heat dissipation of each component is known, and must be applied consistently for all design studies. Create a rule that assigns the part name to its corresponding heat dissipation value. When a model is launched into Autodesk Simulation CFD, the heat dissipation value is automatically assigned to the part. Because each module contains hundreds of these parts, Rules significantly reduce the number of manual steps needed to define the simulation.
The following topics describe procedures for creating and working with rules:
