Hi to everyone!I computed with finite elements a 2D velocity field. I plotted
without any problem the velocity field with paraview. I would like to compute
the gradient.
I tried Filters->Gradient of Unstructured Data Set but without succes.Can you
help me?Thanks,
Nora

Your description is a bit vague to diagnose the issue. Can you share your
data set? I was able to use the Wavelet source, use the Slice filter and
then use the Gradient of Unstructured Data Set without any issues. Can you
see if that works for you?

Thank you for the answer.I think that the dimension of the .vtk file was too
big. You can download the .vtk file from:

In which sense should I use the Slice filter? Sorry but I am quite new with
paraview.Kind regar
It looks like the Gradient of Unstructured Data Set filter isn't working
properly with quadratic triangles. Try using the Extract Surface filter
before computing gradients to convert them into linear triangles.

Thanks Armin.

Alan,
Try selecting the points you want and then plot the selection over time. I
think the current version of plot selection over time creates a series for the
average value of the selection.

I have written an Xdmf file that uses the 3D CoRectMesh to display a
montage of 54 gray scale images. They are laid out in a 9x6 fashion. Each
Image is about 1292x968 pixels. We have run stitching algorithms on the
images to find their correct coordinates in XYZ space so that they will
form the mon
Thank you so much! It seems to really work! :)Just out of curiosity, what
Extract surface filter does? Since velocity is approximated with quadratic
elements, do I loose accouracy using Extract surface filter? Kind

Ken,
I don't think that works. Try the following:
can.exo.
select a few dozen points. plot selection over time. apply.
Notice that it only shows the first point. Select multiple points. (this now
works).
You never get an average.

After a lot of debugging, it turns out the issue is with the SetCells
function of the vtk unstructured grid. Below are the bits of my
Programmable Filter code that are relevant to the seg fault:
output = self.GetOutputDataObject(0)
cellArray = vtk.vtkCellArray()
cellTypes = []
Huh. I'm thinking of the behavior described in bug 0014940. When you make a
query selection, you get statistics like average. When you make a surface
selection (which is essentially an id selection) you get that first point. When
you make a frustum selection, you get an error.
I would report th
Can anybody tell me exactly what algorithm is used to calculate vorticity in
the Compute Derivatives filter? Is it a first or second order central
difference scheme for gradients, or does it use the circulation method?
Thanks.

I can generate surfaces but it seems none of them are based on particle
positions. Anyone know if this is part of paraview functionality?
