Segmentation fault when computing vorticity

Hello, I am running into an issue with computing vorticity using the Gradients function. I have an unstructured dataset with velocity field, and I am trying to computer the vorticity and Q-criterion. However, when I use the Gradient() function to do so, it causes a segmentation fault.

What could be the problem?
