computing the gradient of quadratic triangles giving wrong results
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Computing the gradient of quadratic triangles gives the wrong result. To recreate this issue, load the attached quadratictriangles.vtk, then apply the Gradients of Unstructured Data Sets filter to it. Note that the resulting Gradients array is all 0 while the velocity field itself is varying.
