Well, the curl of the gradient of a scalar field should always be zero, assuming that the scalar field is twice differentiable. If you still want to do that though you can do the following:
1. Apply the Gradient of Unstructured Data Set filter on the scalar variable. You can leave the Result Array Name as Gradients. 2. Use the Python Calculator filter's curl function. The expression will be "curl(Gradients)".
