ALE Incompressible Fluid in LS-DYNA
The computation of fluid forces acting on a rigid or deformable structure constitutes a major problem in fluid-
structure interaction. However, the majority of numerical tests consists in using two different codes to separately
solve pressure of the fluid and structural displacements. In this paper, a monolithic with an ALE formulation
approach is used to implicitly calculate the pressure of an incompressible fluid applied to the structure. The
projection method proposed by Gresho is used to decouple the velocity and pressure
