[Paraview] [Non-DoD Source] XDMF crash

Wed Jan 25 13:13:49 EST 2017

Hello Mr. Burns, thank you very much for your helpful answer. I changed the
XDMF file. But now I have another question.

Now I have problems with GridType="SubSet". ParaView doesn't view the
second and third timestep. Their grids are referenced as SubSet from the
first grid.

This is the reason why I am doing all this: I want ParaView change the
color on a static, fixed, large geometry as quickly as if I switched the
surface coloring variable in the Active Variables Controls dropdown, but
using the time playback features. It is very inconvenient to change the
"timestep" by selecting an other variable in a Color Map drop-down menu
with thousands of entries. Is this even possible in ParaView?

This is my XDMF content:

<?xml version="1.0" ?>
