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

already had this problem with Paraview 3.14.1 but
I received no answer to a first email,<br>
so I tried to investigate on my own since the
problem is still present in release 3.98.0.<br>
<br>
Paraview can not open a Pixie file (it's a HDF5
format included through the VisIt Database<br>
Bridge) when the file includes one timestep only:
Paraview just hangs indefinitely.<br>
Everything works fine when multiple timesteps are
contained in the file.<br>
<br>
I suspect that the problem is connected to lines
618-634 in<br>
Utilities/VisItBridge/AvtAlgorithms/vtkAvtFileFormatAlgorithm.cxx:<br>

//in some case the times and cycles have all

//That kind of behaviour is not possible
currently in ParaView. Instead<br>

if(hasTime && timesteps[0] ==
timesteps[timesteps.size()-1])<br>
{<br>

}<br>
}<br>
</blockquote>
The condition is true not only when the same value
(0?) has been assigned to all<br>
the timesteps but also when there is one timestep
only (timesteps.size() = 1).<br>
Besides these lines were not present in Paraview
3.10/3.12 and these releases<br>
were able to open Pixie files containing one
timestep only.<br>
<br>
Is it possible to fix this problem? That would be
highly appreciated.<br>
Regards,<br>
