**v8.01.103** FDLV103 - Concentric spheres separated by an incompressible fluid
====================================================================================

**Summary:**

This test concerns the field of fluids in the inertial coupling aspect. A modal analysis is carried out of a rigid sphere connected to the massif by springs and immersed in a spherical volume of incompressible fluid.

The test validates the mass calculation added in 3D as well as the modal calculation for a fluid-structure system coupled in 3D.
