Substructuring is a procedure that condenses a group of finite elements into one element represented as a matrix. The single-matrix element is called a superelement. You can use a superelement in an analysis as you would any other element type. By summarizing the mechanical behavior of the bodies, they can be assembled to synthesize the response of a more complex structure, or to model flexible bodies in the Rigid Dynamics solver.

See the Substructure Analysis section for more information about the use of this feature.

Supported Analysis Types

Substructuring currently supports the following analysis types:
