<div>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://<a moz-do-not-send="true"
href="http://portal.nersc.gov/svn/visit/trunk/data/pixie_test_data.tar.gz"

<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 moz-do-not-send="true"
href="http://plutocode.ph.unito.it/"
target="_blank">http://plutocode.ph.unito.it/</a>):<br>

target="_blank">dl.dropbox.com/u/18683007/data.1tstep.h5</a><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

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>

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>
