Dear Paraviewers,
I am trying to visualize Vorticities and Q criterion , for the damBreak case (2D) with catalyst (Paraview 5.5.1). The GradientOfUnstructuredDataSet filter has both of them, unfortunately this filter is not to be found in manifest.json file inside Paraview/Catalyst/Editions/Extras of github. Separately, I've also tried doing the following filters for vorticities, but it wouldnt work. 1) ComputeDerivative() , gives NameError: name 'ComputeDerivative' is not defined 2) python calculator with vorticity(U) as Expression, gives Failed to create 'vtkPythonCalculator' error 3) GradientofUnstructuredDataSet(), again gives NameError: name 'GradientofUnstructuredDataSet' is not defined. Focussing on the last error, could someone guide me on what else could I do I visualize vorticities and Q-criterion in Catalyst. Or perhaps a way to add to the manifest.json file so that my filters work with catalyst, if that would be a better option? Sincerly, Atul Singh.
