This section describes how you can tune feature regeneration using settings in the Feature Options dialog box. You open the Feature Options dialog box by selecting FeatureOptions from the main menu bar. In most cases the default settings will result in acceptable regeneration performance. You should modify the feature options only if Abaqus/CAE takes a long time to regenerate a part or the assembly or if memory consumption is excessive.

The settings in the Feature Options dialog box apply only to the current model and are saved in the model database. If you change to a different model, Abaqus/CAE reverts to the default settings or to any modified settings associated with the new model. The following topics are covered:

• “What is regeneration?,” Section 65.3.1

• “What is a geometric state?,” Section 65.3.2

• “What is a cache?,” Section 65.3.3

• “What are self-intersection checks?,” Section 65.3.4

• “How are position constraints regenerated?,” Section 65.3.5
