Hi,
There used to be a quite useful filter in Paraview called the **GradientOfUnstructuredGrid** , which I was using to calculate the divergence of vector fields.
Unfortunately, Paraview removed this filter from the latest update. Instead, we are left with a confusing and quite difficult to use filter called **GradientpfUnstructuredDataset**.
Applying this filter results in the creation of a confusing set of arrays arbitrarily named from 0 -9 ( ??? ) .
Is there any simple way to bring back the old useful **GradientOfUnstructuredGrid** filter? By means of any plugins?
Or is there any simple way to calculate the divergence of the vector field by means of this new filter in a simple way?

Hi, that question is asked by me. I asked here again because I could not find a valid answer in Stack. Thank you.

No problem. I added the link so that people who find your question here can see the discussion on Stack Exchange.
