Strategy: Suppressing Nonessential Features
Feature interference can occur for a variety of reasons. If you have already built your part and find that Creo Simulate cannot perform a shape change due to the interference of two features, identify the feature that is causing the problem and suppress it if possible. When you suppress a feature, that feature becomes nonexistent from Creo Simulate's point of view.

Do not suppress a feature that carries a load or constraint unless you are doing so to prepare for an analysis type that does not require loads or constraints, such as a modal analysis with rigid mode search.
|
Before defeaturing an aspect of your design, ask yourself the following questions:
• Would suppressing the feature change the behavior of the model?
• Would suppressing the feature eliminate a factor that Creo Simulate should consider during a sensitivity study or optimization?
If the answer to both questions is no, consider suppressing the feature. Otherwise, you need to limit the design variable range to eliminate the problem or, in some cases, rebuild the part using a different development scheme.

If your part includes a large number of datum points that have no use in Creo Simulate, consider suppressing these points before accessing Creo Simulate. An excessive number of datum points can affect performance.
