Samuel,
Thank you very much for the quick reply. I tried your EnSight example
and could select different polygons by using "Extract Blocks" filter.
VTK's example EnSight datasets also allows doing so.
Besides, *.vtp or *.pvtp files are not working for me. What content
should be put into vtp files to enable Paraview "Extract Blocks"? If
you also have a working vtp example that will be very helpful.
Thanks and best regards,
Jimmy

Jimmy,
I have had success with two different ParaView readers doing what you
have described.
It is material domains that I want to examine as distinct. However,
ParaView does not care if it is a serially-generated set of material
domain, a set of processor domain results, or any criterion you want to
use. Each domain needs to be a "displayable graphics object."
Case(1) *.vtp XML format
Case(2) EnSight Gold format using that format's Part-construct.
In either case, ParaView's Extract Group filter allows one to select any
combination of domains to display. Multiple extracted sub-domains can
appear together in one window and/or in separate windows.
A small file that will let you explore this capability is attached.

Hello,
We generate several segments of polygonal meshes and our client wants
to store them into a single file and to view on Paraview. Since the
data contains several pre-segmented mesh pieces, they want to view
each piece separately in Paraview. Is there a file format supporting
composite datasets and has a Paraview interface to show some of them?
We have looked into .vtp and .pvtp formats.
For .vtp XML format, although we can store different segment in
different <piece> tags, Paraview seem to regard them as one piece of
data.
For .pvtp format, each component is stored into a different file,
which is not what our client want.
Although we can always create our reader plugin for Paraview, I am
wondering whether there already exists this kind of file format saving
segments in one file, with a segment-selectable Paraview interface.
Thanks and have a nice day.

Hi,
I think this is an issue with the set up of your cluster. Unless ParaView
uses OSMesa to do rendering it needs a window for rendering.

Andy

Hi All,

I'm annoying by a Paraview catalyst problem. When doing parallel live data
insitu visualization in client-server mode, I have to manually login to all
desktops of all server nodes first, else it'll complain that "cannot
connect to X Server"
* *
As our simulation cluster equips with two CUDA enable GPU cards in each
node, how should I configure it to make Paraview take use of GPU
acceleration function while don't need to login to desktops each time I
decide to launch a parallel visualization task?

I have some fundamental knowledge about parallel visualization with OpenGL
and Cg/GLSL under Linux cluster, that's I have to configure XDisplay under
/etc/X11/xorg.conf and call XOpenDisplay() in my code to make GPU
acceleration available. Does this similar to paraview or help to understand
the Paraview's style?
** **
BTW, is there a way to make the visualization nodes available to multiple
end users? Currently, if one login to the node?s desktop, others cannot
login to the nodes? desktop again.

My environment is a GPU cluster, CentOS and Paraview 4.0.0

Thank you.

Jimmy,
I have attached a file named 'fmavto.pvd' that is an ASCII-text file. It
is a meta-file that references a series of XML-formatted *.vtu files.
ParaView reads the *.pvd file and then knows how to "assemble" the files
referenced within the *.pvd file. The important key-words in the *.pvd
files are 'timestep=...' and 'file=...' Note that the individual *.vtu
files contain the data needed for a displayable graphics object.
The key-word 'name=...' is gratuitous user-information. The key-word
'name=...' for a couple of ParaView versions around 2007 would pass this
user-information to the Extract Block filter; currently (PV version
4.0.1) the ASCII-text strings are no longer passed to the Extract Block
filter.
However, the Extract Block filter does reflect the structure implied by
the *.pvd file; the filter simply uses the ubiquitous and
not-very-helpful C-language off-set addresses of 0,1,2,3,... for the
block names.
Because of the large number of ASCII-text files that can be generated in
a transient dynamic simulation with multiple material domains using the
vtk-formats, sometime back I switched to the EnSight binary-formatted
output. In this format it is possible to provide names that will appear
in the Extract Block filter.
Hope this helps,
Regards,
Sam Key

After you run the IntegrateVariables filter, you probably see the results in a
new spreadsheet view. Just select the row containing the integrated variables
and run the Plot Selection Over Time filter.

Subject: [EXTERNAL] [Paraview] Plotting an integrated variable over time
A customer of mine asked the following:
Hello,
I am trying to plot a variable that has been created using the PythonCalculator
filter. First, I create a Cell variable. Then, I would like to integrate/sum
all values for this variable and plot this result as a function of time.
I can use the "IntegrateVariables" filter to look at results individually, but
how can I create a variable that can be plotted within ParaView?
Thanks,
Alan
