You should be able to open up all of the .vtu files at once in ParaView
and then step through them using the built in UI.

In general, the kinds of simulations that PyFR is used for are of
sufficient scale that it is simply not practical to work with more than
a single solution file at a time.  As such there has been no work around
merging multiple files together.
