Dear ParaView developers,
I'm trying to compute gradient of my x-component of velocity on a
grid of tetrahedra which has 55244 DOF. 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.
Martin Vymazal
