1. But

Estimating the quality of reduced models in the context of modal analysis. This command makes it possible to calculate the work of the residual coupling forces at the level of each of the interfaces, as well as the work of the residual forces on the internal parts of the substructures.

In addition, based on this work, the command calculates enrichment terms, based on:

• the work of residual forces at the interfaces, for each substructure,

• the work of the residual forces on the internal parts, for each substructure,

• the differential movements (detachment) that may appear at the interfaces between the substructures.
