Product: Abaqus/Standard
Benefits: The substructure retained degrees of freedom no longer have to be constrained in the frequency extraction step.
Description: Free or mixed interface eigenmodes can now be selected to generate a dynamic substructure. You can get a better approximation of the model's dynamic response with fewer dynamic modes when using free or mixed interface eigenmodes as compared to using a fixed interface. The dynamic substructure also enables retention of nodes from the “cloud” of a distributing coupling.
