Hello everybody,
I'm searching for a program to write some .DAT files in .VTK format. (for *
Paraview* visualization)
These .DATs contains grid structure(bathymetry), lat, long, scalars and
vectors. I'm writing them *manually* in .VTK, like these:
# vtk DataFile Version 3.0

Hi all,
Please excuse my newbie question - I'm a new ParaVIEW user this week.
I have a time-series dataset generated from the MFIX CFD code that I
want to visualise. I have no problem loading and displaying the data.
I can generate an isosurface, for example, and animate such that the
Actually, this seems to be a bug in the reader. Creating the contour
and then hitting play should just work. I tested and it does not. We
will look into it.

Oops. I didn't notice that it was a "steady state" flow field. The
TemporalStremTRacer expects unsteady flows, however it would be quite
simple to modify it to use a single step. (I think easier than taking
streamlines and animating particles along them - though thinking about
it, the

this is exactly the technique I use. Generate streamlines. Then
iso-contour the streamline object with the scalar field
Interesting. I guess the biggest challenge of doing this in our
pipeline would be finding the time range. Ideally, the integration
should continue until all particles leave the domain or get stuck in a
stagnant region. That would require integrating them first and then

I just tried to use ParaView from Tuesday's CVS (The network was down
last night.) on both CPU cores to volume render a large (1/4 the size of
available RAM) image.
As soon as I selected volume render for the representation I saw the
status bar show PKdTree and moments later all of the system
Do you have any unstructured data being rendering in the scene?
KdTree is used to distribute that unstructured data in accordance with
the partitions provided by the structured data.

No, just one big .vti image.

Kevin,
The KdTree is still built (using the partitions from the structured
dataset set itself -- hence isn't a very compute intensive task) just
in case it's needed to partition any unstructured data, hence you're
seeing the PKdTree progress. But I don't think that's where it is
hanging. Is the
Ah and there's the bad news.
In case of image data for the if condition at vtkPKdTree.cxx:435,
I'd expect the condition to succeed and go to
this-ProcessUserDefinedCuts(..) however, it seems like that condition
is failing and it's going to this-MultiProcessBuildLocator(..) which
is used for
That's a really cool solution. Bravo Jean.

This conversation has basically become academic, but it would also be pretty
easy to create a filter that reported a bunch of time steps and just passed the
same data every time. The particle tracer would thing it was a time varying
data even though it was not.
Jean's solution is still easier
Kevin,
Attached is a patch. Can you verify that it works after applying the
patch? If so, I'll commit it to CVS.
Thanks

Yup that fixed it. The PKdTree completes immediately and then I get my
volume rendering.
Thank you!
Sorry, but this doesnt make any sense to me. I have a 3D dataset with
magnitude and velocity (X,Y,Z) for 13 time frames. And as you wrote,
paraview internally converts multiple vktDataSets into a TemporalDataSet.
But particle tracer requires multiple time steps, why does it then give
error that a
