Yup. It looks like a bug. In fact, compute gradients seems to crash whenever the output tensor is set to nothing (and is otherwise valid). I submitted a bug for this:

So, this happens when I have the parameters set as 1- "Vorticity" as the Output Vector Type. 2- "Nothing" as the Output Tensor Type. If I choose "Strain" or "Vector Gradient" for the second part, it seems to work. Attached, I also have added the vtr file I used. Feel free to test it to find the problem I had mentioned.

This is what I do: >Calculator: to get u_vector = ux*iHat + uy*jHat >Compute Derivatives: to get Vorticity As soos as I press Apply, Paraview crashes without any error. I have used several versions of Paraview and I get the same problem on linux machines. Could this be a bug?
