v8.01.105 FDLV105 - Mass added to an axisymmetric piston coupled to an incompressible fluid column

Summary:

This test in the field of fluids uses a modal analysis on a coupled system with an incompressible fluid structure such as a piston fluid column with a free surface. The piston and the fluid are modelled respectively by axisymmetric mechanical and thermal elements. The calculation of added mass in an axisymmetric configuration is thus validated.
