Hello All,


I am trying to visualize the skin friction coefficient on the surface of an aircraft wing while overlaying an oil flow type visualization. I am doing this in Paraview with Plot3D (structured) files, which is where things are getting tricky.



In order to calculate the skin friction coefficient, I need to use "extract subset" on the wing surface to have the surface normals for dotting with the velocity gradient; however, once I do this I don't have the volume information anymore to use velocity/momentum for the surface LIC. I have tried "Resample with Dataset" to have the volume data available with the surface calculation of the skin friction coefficient, but rendering LIC looks like a TV with no signal. Does anyone have any thoughts?
