More information please. How are you extracting the x-component of the velocity? What filter are you running to compute the gradient? Would it be possible to post some example data that exhibits the problem so that we can replicate it?

ParaView fails to compute the gradients with the following error message: Generic Warning: In /home/kitware/Dashboard/MyTests/ParaView-3-8/ParaView-3.8/ParaView/VTK/Common/vtkMath.cxx, line 1338 Unable to factor linear system The mesh does not have degenerate/ugly elements, but it has some sharp edges (in the inlet/outlet area). Is this a problem? If not, is there a way of avoiding the error? Thank you very much.
