[Paraview] Animation in Paraview

[Eric E. Monson]

Hey Natalie,

I can reproduce this with PV 3.6.1, but it works fine in CVS now. I  
think it's been fixed because of all the recent work on the XDMF  
libraries.

It used to be that the vtkXdmfReader defaulted to the first data frame  
(time step) if it was ever asked for a time step which didn't really  
exist. (This is in contrast to something like the PVD reader which  
would default to the previous valid time step.) I'm guessing that this  
is why the Real Time and Sequence don't work right with 3.6.1 --  
they're asking for non-existing time steps and being given time step 0.

As a workaround, place a "Temporal Snap-to-Time-step filter after your  
XDMF reader in the pipeline, and set it to NextBelowOrEqual and things  
should work right.

Talk to you later,
-Eric
