Dear all,
I'd like to know how to probe cell index number of unstructured grids.
For example, after loading unstructured data (typically Hexa or Tetra),
I hope to know the cell index like below:
1) set x, y, and z
2) automatically probe the index number of the cell that includes the
above (x,y,z
Sorry if I was not clear.
Ideally I'd want to do the following:
1) click on a PolyData in the pipeline
2) go to Filter->ReadAndApplyTransform.
3) It should then ask me which transform file I want to read (the
"reader" functionality" I mentioned). My vtkReadAndApplyTransform
would then read this
Hello,
you're right. I didn't notice that some of the elements have
negative volumes. Thank you very much.

After taking a look at your mesh, I see that the problem is that you have some
degenerate tetrahedra. That is, there are tetrahedra where all 4 vertices are
in a plane. In this case the tetrahedron is self-intersecting and the gradient
is ill-defined (over constrained I believe), which is why
I have compiled osmesa 7.5.2 and the newest release candidate osmesa 7.8.3-rc1.
Unfortunately pvbatch 3.8.0 using either of these libraries gives the same
output and the render error persists. I use the following command to configure
/ compile the osmesa library:
./configure --with-driver=osme
Hello Ken,
I computed the x-velocity component using a calculator filter. Then
I applied the 'Gradient of Unstructured Data Set' filter to the output
of the previous filter. This is the place where the computation fails.
I sent you the data in a private email.
Best regards,
Martin Vyma
It may also be possible to create a composite filter in

Composite filters rather readers are indeed supported and will wor
It's not clear to me exactly what the original question is asking. Are you
simply trying to define both a reader and filter in the same plugin? In that
case, you provide two ProxyGroup elements in the server manager definition and
place the reader and filter in the appropriate one.

More information please.
How are you extracting the x-component of the velocity? What filter are you
running to compute the gradient? Would it be possible to post some example
data that exhibits the problem so that we can replicate it?

Hello,
Yes, you can build custom (branded) versions of ParaView with 3.8. You can
either build ParaView and all of its supporting libraries from source, and then
build custom applications against that build, or you can now download a

Easiest solution would be apply the transform within the reader
itself. You can easily create a vtk-level subclass for your reader
that can do that. Then this is just a reader.

Dear ParaView developers,
I'm trying to compute gradient of my x-component of velocity on a
grid of tetrahedra which has 55244 DOF. ParaView fails to compute the
gradients with the following error message:

Yes, it possible. You may want to look at the Wiki for details:

Hi everyone,
I would like to know if it is possible to build a custom paraview (withe
version
3.8) in a specific directory out of Paraview directory source code (the same
for
a plugin).
I guess it is possible but I am new with cmake configuration and I would like
to
know how to do this.
