748 New Member manas Join Date: Feb 2016 Posts: 1 Rep Power: 0	I am analysing compressible flow of mach 0.8 past cylinder(2D) . In flow field i initialized left side as pressure far field and right side as pressure outlet. I have set operating pressure to 0 pa and gauge pressure to 76000pa . I am getting cd = 40 and cl = -8 and more abrupt results . Why? I am using K - omega turbuelence model...with density based solver.
