Hi Claudio,
I have correct Pixie reading in Paraview next.

Dear Utkarsh,
thanks for trying to look into it.
These are some datasets distributed with VisIt to test the
Pixie output
blockedhttp://portal.nersc.gov/svn/visit/trunk/data/pixie_test_data.tar.gz
<http://portal.nersc.gov/svn/visit/trunk/data/pixie_test_data.tar.gz>
As you will notice Paraview 3.14 or newer can not open the
file pixie_expressions.h5,
while it correctly opens all other files (pixie3d3.h5,
...), where the only difference
between the files is the number of timesteps contained in
each of them.
The following files are written by the code that we develop
(http://plutocode.ph.unito.it/):
blockedhttps://dl.dropbox.com/u/18683007/data.2tstep.h5
<http://dl.dropbox.com/u/18683007/data.2tstep.h5>
blockedhttps://dl.dropbox.com/u/18683007/data.1tstep.h5
<http://dl.dropbox.com/u/18683007/data.1tstep.h5>
Paraview 3.14 or newer can open data.2tstep.h5 but hangs
when trying to open data.1tstep.h5.
These files contain 2 and 1 timesteps respectively, but
their structure is exactly the same
(groups, attributes, datasets, etc etc ...)
Previous versions of Paraview (down to 3.10) and VisIt (up
to the current release 2.5.2) can
correctly open all the files. Therefore I suspect that the
problem is somewhere in the bridge
from VisIt to Paraview of the two most recent releases.
I have always used the pre-compiled binaries for Mac OS X
64-bit Intel.
Thanks again,
Claudio

Claudio,
Do you have any sample dataset that I can use to test
this/the fix?
Thanks,

I already had this problem with Paraview 3.14.1 but I
received no answer to a first email,
so I tried to investigate on my own since the problem
is still present in release 3.98.0.
Paraview can not open a Pixie file (it's a HDF5
format included through the VisIt Database
Bridge) when the file includes one timestep only:
Paraview just hangs indefinitely.
Everything works fine when multiple timesteps are
contained in the file.
I suspect that the problem is connected to lines
618-634 in
Utilities/VisItBridge/AvtAlgorithms/vtkAvtFileFormatAlgorithm.cxx:
//in some case the times and cycles have all
zero values.
//This is caused by a file reader that
generates the time value
//once the reader moves to that timestep.
//That kind of behaviour is not possible
currently in ParaView. Instead
//we will force the reader to generate the time
values for each timestep
//by cycling through everytime step but not
requesting any data.
if(hasTime && timesteps[0] ==
timesteps[timesteps.size()-1])
{
//we have hit a timestep range that needs to
be cycled
for(int i=0; i < timesteps.size();++i)
{
this->ActivateTimestep(i);
//Nek and other readers don't update the
time info intill you
//call gettimes.
this->AvtFile->FormatGetTimes(timesteps);
}
}
The condition is true not only when the same value
(0?) has been assigned to all
the timesteps but also when there is one timestep
only (timesteps.size() = 1).
Besides these lines were not present in Paraview
3.10/3.12 and these releases
were able to open Pixie files containing one timestep
only.
Is it possible to fix this problem? That would be
highly appreciated.
Regards,
Claudio
