Model Reduction and Superelements with NX Nastran

Superelements automate the process of creating reduced representations of components with significantly fewer degrees of freedom and can efficiently assemble them into a system model. Superelements can be especially beneficial when:

• An assembly of all component models representing a system is too large
• Some component models are proprietary
• Design studies will be performed where most of the system remains unchanged
• Nonlinearities in a system can be isolated to a small region
• Models for a system do not follow unique numbering schemes

Top-Level Overview Whitepaper – describes the different types of superelements along with further considerations.

Theory and Implementation Whitepaper – provides a background on superelements and describes workflows for the three primary ways of creating and using superelements.
