**r4.02.02** Elements for coupling fluid-linear structure interaction with inert fluid
===============================================================================================

**Summary**:

The elements described here make it possible to perform calculations of the frequencies and natural modes of a structure coupled to a fluid. They also allow the calculation of acoustic response.

After the formulation of the fluid-structure coupling problem, this document describes the approach followed to implement the new finite elements.
