I have used various versions of ParaView in the past and taken advantage of the “Compute QCriterion” option under the GradientOfUnstructuredDataSet filter. I have recently been working with data sets on a remote server where ParaView 5.9.1 is installed. Unfortunately when using the GradientOfUnstructuredDataSet filter the “Compute Divergence”, “Compute Vorticity”, and “Compute QCriterion” options are gone. For this version of ParaView were they moved elsewhere? Or perhaps is there an easy way to emulate them with the Python Calculator filter?

Thank you very much, can’t believe that wasn’t the first place I looked!
