<tt>To followup a bit, attached are two images of the issue I am
seeing.<br>
<br>
The two-lobe rendering (from another package) is correct.<br>
The single lobe that is rendered with ParaView is incorrect.<br>
<br>
And if somebody would be kind enough to download the sample data
and verify what I am seeing:<br>

</tt><tt>And/or if anybody knowledgeable on the xdmf or paraview
source code can suggest an area of the code to look at, I can dig
in to figure out what's going on.<br>

<div>I've never tried to use VxVyVz type geometry before, but I
wonder whether it's some sort of problem with you trying to
specify polar coordinates when it's expecting XYZ? You might
want to play with a smaller sample file that just uses light
data first, and then if you get that working you can make sure
the same sort of arrays exist in your HDF5 file. Here's a sample
that I modified from one of the standard Xdmf example data files
(and which loads in ParaView 3.8.1 fine on my machine):</div>

<div class="moz-text-html" lang="x-western"> <tt>Hi,<br>
<br>
We have a 2D Uniform grid data set in XDMF format that
we are trying to visualize with ParaView. The data is
stored in a 1MB HDF5 data set. The (light) meta xdmf
file is attached to this email.<br>
<br>
I am seeing some problems when trying to load the
data-- usually ParaView either crashes, or the data
does not show. I have tried the PV 3.8.1 Windows
binaries as well as building ParaView from source that
I pulled a few days ago from the <a
moz-do-not-send="true"
href="git://paraview.org/ParaView.git">git://paraview.org/ParaView.git</a>
repository.<br>
<br>
After loading the data and hitting Apply, the 3D
render window will be empty. What I've noticed is that
the Y-range of the Bounds will sometimes be extremely
large. For example here is a snapshot from the
Information tab:<br>
<br>
</tt><span><moz-screenshot-4.png></span><br>
<pre><tt>Are these known issues with ParaView?
Or perhaps the data is mal-formed, I am new to XDMF, so it'd help to know if there is an error in the .xmf file.
HDF5 tools like HDFView and h5dump don't report any anomalies on the HDF5 file that goes with the heavy data.
thanks</tt>
