<p class=MsoNormal><span lang=EN-US>However, the animation works fine for me
from the xdmf time series. From what I understand, your script handles several

Jean-Michel,<br>
<br>
For what it's worth, we never had much luck when we tried using XDMF time
series (back in the early PV version 3.14 days). So we instead just got in the
habit of looking at individual snap shots and if we wanted to do an animation,
we would use the Python trace feature to set up our view and then make some
small modifications to the generated trace script. We would wrap all of the
contents in a function that took in a file name/number and output an image at
the end and then we would write a small driver program that would call that
function, looping over our temporal series that way.<br>
<br>
It has the added benefit of running the visualization on a cluster where each
process is serial and handles a range of data files. <br>
<br>
Hopefully somebody who has gotten temporal series to work can help you out. If
not, I'll be happy to share some example scripts for processing time series
data as snapshots using pvpython.<br>
