[Paraview] Problem with Compute Derivatives Filter

[Moreland, Kenneth]

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:

Thanks for narrowing down the problem and reporting it.

Hi Ken,

I narrowed this problem down a bit.
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.

Best,
Mohamad

It could be a bug, but I cannot replicate it.  Any chance you could send some sample data?

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
