In this video I describe the process for generating a c-grid topology for the NACA 0012 airfoil geometry by extrusion. A normal hyperbolic extrusion coupled with a translational extrusion in the wake were used to define the c-type topology. The benefit of this approach is that by using the hyperbolic extrusion utility in Pointwise, no post smoothing operations using the elliptic solver are necessary as the grid is highly orthogonal and normal to the surface.
