Hi Both, Yep the 2.5D Compressible code has not been extensively tested or validated (certainly not to the detail that we have tested the incompressible solver). So for now we have been using strips of the 3D solver in our own tests so I would recommend using that version of the code. Thanks, Spencer.

Perhaps, using fully 3d in your simulations may be a better option. Is my suggestion correct?@Spencer.

I have tested it in Incompressible flow solver. It is fine. So I think maybe there is a bug in the compressible flow solver. But I am not looking deep into the code. So I can not find the problem. If someone has a solution, please let me.
