[Paraview] time series with Xdmf-Files

[Eric E. Monson]

Hello Natalie,

I don't know if this will be helpful (since you already have all of  
those XMF files), but the standard way of doing the time animation  
with Xdmf and ParaView is to have all of the time steps in one XMF  
file as a "temporal collection". Each time step in the file could  
refer to a separate HDF5 file for its data. There are ways of enabling  
animation for a series of files using a time-unaware reader in  
ParaView, but I think it would be easier to write a script to combine  
all of your XMF files together into the time-aware format that is  
supported by Xdmf.

I'll put an example below.
