.. _V8.01.105: **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. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Synth_se_des_r_sultats
