[Paraview] Problem with Compute Derivatives Filter

[Mohamad M. Nasr-Azadani]

Hi all,

I am trying to compute the vorticity vector from a 2D dataset.
My dataset file is .vtr format.
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?

Thanks,
Mohamad
