I designed an airfoil in Design Modeller by importing coordinates from a .txt file. I was assigned to generate C-topology mesh in Pointwise. I imported my model in Pointwise, created the mesh but when I import it back into FLUENT, I always get the error for Negative Cell Volume.
I have attached an image that shows the inner area of my foil and I think that the problem is right here. The mesh shouldn't be inside the foil. Can someone point me in the right direction? Thanks in advance. |

There should not be any mesh "inside" the airfoil. It looks like the domains are folded over on each other. If it is small, ZIP the pw file and attach it here.
