Hi Lorenzo, I assume you are using OpenFOAM based on your previous questions. The command 'wallGradU -latestTime' will give you the gradient of the velocity at the wall. This vector can then be used as input for the surfaceLIC representation to create oilflow like images. I am not sure if surfaceLIC works on all type of cells. In older versions of paraview I needed to convert my structured surface mesh to triangles first using the filter tetrahedralize.

Maybe I'm missing something but I don't get anything? Once I've built the vector as U_X*iHat+U_Y*jHat+U_Z*kHat with the calculator, what should I do? Also, as my velocity is 0 on the surface, I think this vector I built equals (0,0,0) everywhere? Isn't it?
