hello everyone i m simulating an 3D airfoil and the mesh isn't fine after using snappyHexMesh that's what we see on paraview:
thank you for answering me
best begards

Either increase the refinement levels on the airfoil surface or make your base mesh size smaller. Your local cell size is too large for the snapping to happen accurately. You also might want to extract your feature edges into an eMesh and turn on explicit feature edge detection. Good luck.

thank u for replaying Dan
i diid whatt u suggested to do but nor good résults, i m still trying now.
