[Paraview] XDMF and non standard topology

2012-08-23 Thread Adrian LUCA
Hello,

I'm working with an unstructured triangular mesh and the elements which are 
forming the mesh are not a paraview standard (small triangles are contained 
inside each element--elements are triangles too). I 
created a XDMF file where i've put in a collection all my elements (for the 
triangles inside each element i used a standard triangle topology). I have two 
questions:

1) Is there any other way to do this, because paraview takes a lot of time to 
load this one?

2) It is possible to create a link from a XDMF file to a line or a column of a 
matrix found in a HDF5 file?

Thank you very much!

Best regards,

Adrian___

[Paraview] PV 3.14.0 reset center

2012-08-23 Thread Stephen Wornom
I see the icon reset center. I want to reset the center from 0,0,0 to 
0,0,10.

What are the steps to reset the center?
Thanks,
Stephen
p.s.
Must I reset the center before making a slice?

Subject: Re: [Paraview] Numpy masking (via programm filter) not quite working 
in parallel
 
Hello,

I have done some work in VTK towards that. Currently, this works only
with structured data.

If your data is structured, you can use vtkPStructuredGridConnectivity
to generate a bitmask (an unsigned char associated with each mesh
node). The bitmask can then be queried using the vtkGhostArray (See
http://www.vtk.org/doc/nightly/html/classvtkGhostArray.html) to see
which properties are turned on for the given mesh node. If the
IGNORE property is ON, that means that the node is a duplicate with
respect to the given process and should not be taken into account. The
implementation assigns ownership to the lowest rank of a mesh node --
on all other processes, the IGNORE property is set to ON.

TestPStructuredGridConnectivity illustrates how this can be used. The
test ensures that:
(1) Ensuring that the total number of nodes computed is invariant to
the number of processes/partitions
(2) Ensuring that computing the average for a given field is also
invariant to the numer of processes/partitions

If this could be useful in your work, I can elaborate more if you have
any questions on how to use it.

Best,
George

 Hi Sohail,

 ... Will this point sharing information become available in later versions
 of ParaView? i.e. would it ever be easy to identify and count duplicates?

 I don't know of any plans to implement this (but that doesn't mean there
 aren't).

Re: [Paraview] Python interpreter not being created for coprocessing?

2012-08-23 Thread Andy Bauer
It looks like you've built it properly. At least I don't see anything that
looks wrong. I think the reason you didn't get any coprocessing tests is
that they depend on ParaViewDAta. Maybe the next step is to download
ParaViewData (git://paraview.org/ParaViewData.git) and then set the
location ParaViewData in cmake. After that, run the coprocessing tests
(ctest -R CoProcess) and show me the output from that.

 Hi Mark,

 I think I can guess what the problem is but can't be certain without some
 more information. My guess is that you're using ParaView 3.14.1 for this
 and you're trying to use the fortran interface but haven't built ParaView
 with Python enabled. There were some dependency issues there that have been
 ironed out since then though. If that's not the case though I'll need more
 information on versions and maybe sending your CMakeCache.txt in your
 ParaView build directory.

Not possible for most, if not all, tests. The reason is that the test
doesn't get added unless ParaViewData is available.


 And 2, is there a way to tell ctest to not use MPIEXEC_MAX_NUMPROCS when
 running tests?


Many parallel tests, including the parallel coprocessing test, usually just
have it hard coded to use 2 or 4 processes for testing.

[Paraview] Xdmf Binary File Integer Bit width

Re: [Paraview] ParaView thinks that it does not have a wind blade reader

2012-08-23 Thread Andy Bauer
Hi Sohail,

Sorry for the slow reply but I wanted to make sure how things should work
first and that took a bit to figure out. Anyways, this is closer to what's
needed but the way it is supposed to work in VTK is that we use
vtkObjectFactory to determine which one should be created when
vtkWindBladeReader::New() is called. This is done at build time based on
whether or not VTK is built with MPI. So if VTK and ParaView are built in
parallel then there is code added that creates a vtkPWindBladeReader when
vtkWindBladeReader::New() is called. This is regardless of whether or not
the executable is run with mpi initialized or not. Because of this, the
parallel version of the reader is responsible for checking whether mpi is
initialized, ideally by doing
vtkMultiProcessController::GetGlobalController()-IsA(vtkMPIController)
is true, and if it isn't it should just call the parent class's methods for
reading in the files. You may want to look at vtkPNrrdReader and the
CMakeLists.txt file in that directory to see how they did things. Note
though that if it's a single process running that it doesn't do any MPI
calls even in the parallel version so your code will be slightly different
than theirs.

As for other parts of the email below:

1) yes, please keep cc'ing the list as there are some details in here that
will be helpful to other people trying to implement their own parallel
readers or filters

2) I'm not sure what's going on with the gradient filter but am guessing
that it has to do with the multiblock data set and that there probably
isn't that same array in each block. But that's just a guess. Did you try
extracting the air block and do the vorticity and/or q criterion
computation on that?

3) vtkSMReaderFactory may be the class you're looking for to determine
which reader is getting used. ParaViewReaders.xml has a list of readers
that it will try to read in a file.

 Here's the first version.  Do you want me to keep ccing the list? Not sure
 if that's necessary at this point because this is related to the
 development of ParaView and not help.

 I've run it with an older version of the master, and it seems to read in a
 test .wind file just fine.  For now I had to store the vtkPWindBladeReader*
 files into VTK/Parallel/MPI since I don't have VTK/IO/MPIParallel module
 yet.  Now when I run the gradient filter after the field, the gradient
 filter thinks that the input array does not have the appropriate number of
 components for Q criterion or vorticity...but it should (UVW does have
 three components per tuple).  Might be my outdated copy of the git repo.
 Haven't debugged that gradient code yet.

 *I was wondering if this is the type of code that you want?  Or should
 the classes be designed differently?*  Also, I have only run it parallel
 because if I try to instantiate it inside of the python shell in serial it
 tries to run RequestInformation (which assumes that the file path exists
 but does not).  It's a work-in-progress but it's a start.

 A random question: if ParaView reads a file, where would I put a
 breakpoint that tells me which reader it ends up picking??  I have some
 separate VTK code that reads in a rectilinear grid, but does not generate
 cell/bounds information. ParaView does generate information about the
 bounds though.

 Thanks.

 In today's git master it now sits in VTK/IO/Parallel/vtkWindbladeReader.

 The serial version should go in VTK/IO/Geometry.

 The MPI version should go in a new module VTK/IO/MPIParallel.
 (VTK/IO/Parallel depends only on vtkSocketController now and should
 not depend on vtkMPIController).

 Finally when that is done we can remove the flag in paraview's xml
 that prevents it from being used in serial.

Steve,
I am pretty sure that functionality was lost a few years ago when we went to PV 
3.0.  Please write up a feature request?

Thanks,

Alan

I see the icon reset center. I want to reset the center from 0,0,0 to 0,0,10.
What are the steps to reset the center?
Thanks,
Stephen
p.s.
Must I reset the center before making a slice?

[Paraview] Can I use ParaView remote rendering while on remote desktop?

2012-08-23 Thread Alexis Chan
Hi

I started a ParaView server using:
./pvserver.exe testheadtracking.pvx

And a client using:
./paraview.exe(Then I successfully connected the client to the server
using the ParaView UI)

The render server window (titled Visualization Toolkit - Win32OpenGL #1
is frozen, and I could not see what is rendered in that window. I attached
the pvx file (even though it is called testheadtracking.pvx, I have not
started the VR Plugin).

Is this due to the fact that I am connected to the client and server via
remote desktop?

Thanks.
