Basics : Dam break

This LS-DYNA simulation shows a simple free surface example using the ICFD solver. A column of water collapses under the load of gravity. In order to set up such a problem, the domain must be divided in two ICFD_PART_VOLs, one for the fluid, one for the vacuum. For the automatic volume mesher to recognize the initial interface, the keyword MESH_INTERF must be used. Gravity load is applied through the use of LOAD_BODY keyword. Since the solver is implicit, no ramp up is needed.
