A recently developed transient, two-dimensional, finite-element shock capturing scheme is applied to the study of shock interaction with a box suspended above a rigid surface. The results demonstrate the excellent resolution of the captured shocks and the application of a newly developed adaptive refinement/coarsening algorithm. In addition to interesting shock propagation and interaction processes, the results demonstrate the capability of the new code to capture, and define in great detail, vortices shed from the downstream corners of the box. The ability of the new scheme to model such fluid dynamic phenomena as shock-shock, shock-surface, and shock-vortex interactions, as well as vortex dynamics, are demonstrated.
