Quadrature C — Welcome to LS-DYNA Examples

Home » Knowledge Base » ALE » FSI » Quadrature C

This models a bar impacting a water surface. File quadrature_C.k is Eulerian with 1st order advection and a single material for the water. *INITIAL_VOID_PART command is used to model the space above the water surface. Three quadrature points are used for the coupling.
