So I guess you are using quads on the surface of some curved geometry? What you may be able to do it extrude those to produce a layer of hexahedral elements. I think you can then use farfield in Pointwise to help prevent the quad bases for the pyramids from being anything other than parallelograms. However, I haven’t used this procedure before and it will be dependent on your geometry.
