<br>
I can venture a guess. The relevant error message seems to be:<br>
<br>
--8<--<br>
VisIt: Message - Rendering window 1...<br>
VisIt: Error - The compute engine running on <a href="http://crcfe01.crc.nd.edu" rel="noreferrer" target="_blank">crcfe01.crc.nd.edu</a> has exited<br>
abnorm<br>
ally.<br>
VisIt: Error - Scalable Render Request Failed (VisItException)<br>
viewer: Obtained null data reader for rendered image for engine<br>
crcfe01.crc.nd.ed<br>
u.<br>
--8<--<br>
<br>
I have seem odd image corruption when VisIt could not read the image<br>
out of the OpenGL buffer it uses for rendering. <br>
<br>
I would try the following: <br>
<br>
* first try and see if you can open rho.xy.h5 in VisIt manually, you<br>
may have to make sure that the CarpetHDF5 reader is used<br>
* then make a PseudoColor plot which should show one of the stars<br>
<br>
if this works then at least VisIt can read the files and render them.<br>
<br>
In that case you may have to play with the "screen capture" setting of<br>
VisIt's save window functionality (which is what is used to create the<br>
images).<br>
<br>
In the python script, add this line:<br>
<br>
s.screenCapture = 0<br>
<br>
and if this does not help, try<br>
<br>
s.screenCapture = 1<br>
<br>
If you could include one of the images that may help.<br>
<br>
Yours,<br>
Roland<br>
