From my expereince you can do it a decent job of it with flwo Sim. Autoadaptive meshing needs to be on, maybe start at a slow lower supersonic speed and use the results from that speed as IC's for higher speeds. Use symmetry if suitable. Expect large cell counts and long compute times. Make sure the ratio of partial cells to other cell types is les than 1 (do not have a partial cell dominated model - takes to long to compute).
