Missile separation simulation with control laws

Using an overset unstructured grid, three dimensional URANS equations are applied to simulate the missile separation with control laws. The walls criterion is used in the automatic holecutting procedure. Arithmetic average method is used to get the value during the overset grids. Comparison computing of the trajectories of a wing/pylon/finnedstore configuration with three different control laws is carried out with this method, and a complex separation problem is solved.
