Biconvex airfoil simulation in supersonic flow

      Hello, I am an undergraduate student and I am fairly familiar with the software (FLUENT). I have been trying to do a supersonic simulation on a biconvex airfoil(6%thickness).y

      I didn't found the pressure coefficient curve satisfactory. On the right portion of the curve it seems abnormal. I used density based solver with sst kw turbulence model. My meshing and other set up along with cp curve are attached here.

      I would appreciate your valuable feedback on this purpose.

      You've got a large jump in cell size as you transition between blocks, similarly on the leading edge there looks to be a section where you skew the hex mesh which may tie up with the spike in the lower part of the curve.

      Thank you, Mr. Rob. I am really sorry for being so late.
