[Paraview] post-process of CFL3D result with surfaces in paraview?

[Stephen Wornom]

I have a different code but had the same problem that I resolved by adding an additional variable which sets value 0 at interior points and a different values for each surface, for example, -3 for the wing surface points. Then I use "extract" to visualize the different surfaces. 
Hope this helps, 
Stephen
