Lagrange hexahedron Gradient and Vorticity fails
In regard to the below discourse post: https://discourse.paraview.org/t/vorticity-and-gradient-calculation-numerics-gives-wrong-result/1514?u=vrkssai
The filter "Gradient of Unstructured data" and Vorticity Calculation using python calculator for Lagrange Hexahedron Grids give erroneous results. I have laid down the steps to reproduce it in the post.
