I have a external aerodynamics case from OpenFOAM in which I want to visualize the Q-criterion and vorticity fields. I searched in the internet regarding this and I found that I have to use a filter called `Gradient Of Unstructured DataSet` however when I use Cntrl+Space and search for this filter it is not available in fact the only filter that matches is gradient filter. Please help.

It has been integrated into the generic Gradient filter.
