Basics : Plate flow

This LS-DYNA simulation shows a simple ICFD input deck with a coarse mesh. It shows how the solver deal with infinitely thin plates or shells in 3D. Since two nodes are needed in order to solve for the pressure difference between the two faces of the plate, the automatic volume mesher will generate an extra node and 'pull' a little on the mesh leaving a tiny gap between them, considered infinitely small compared to the size of the problem. This is done through the introduction of the keyword MESH_EMBEDSHELL.
