my analysis is for supersonic case, my Pc = 6.895e+6Pa and Tc = 2777.778 K and Pa and Ta for ground ambient conditions.
Does that means for supersonic rocket nozzle analysis, the boundary conditions which I have used, are correct and I only need to focus on Mesh around jet due to presence of shocks or expansion waves ?
Can you please confirm this, If boundary conditions are correct then I think I don't have to worry about that part for the least. So that I can focus more on meshing around jet, as making structured mesh is becoming difficult due to slanted part of nozzle.
