v2.04.101 SDLV101 —Beam in dynamic substructure

Summary:

The problem of determining the natural modes of an embedded beam is considered.

To do this, a dynamic substructuring methodology using imposed interface modes is used (see U2.07.07 for more details).

The ability of the approach to represent the modal behavior of the global structure is shown.
