**v2.04.103** SDLV103 —Lyre closed with IFS dynamically substructured
===========================================================================

**Summary:**

We consider the problem of determining the natural modes of a pipe filled with water in the shape of a lyre closed in on itself with consideration IFS.

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.
