r4.02.04 Fluid Coupling - Structure with Free Surface

Summary:

The fluid/structure coupling is presented here in the case where the fluid has a free surface. Free surface elements have been implanted in*Code_Aster* to calculate the swaying modes of a fluid coupled to an elastic structure for a three-dimensional problem.
