Inlet--supersonic inlet (P,U,T) specified. Outlet--Extrapolated outlet (dp/dn,du/dn.dT/dn=0), since flow at outlet is supersonic. top of channel--symmetry(to simulate an infinite domain). bottom of channel before ramp--symmetry. ramp--slip. When i run the case with these bc's, the solution blows up. I would appreciate it if someone tell me what i am doing wrong Regards Srinath
