Why not follow what is done in Ensight case files?! In Ensight format you just
specify the pieces of data by listing it in a case file. The same thing should
be straightforward with XML-based VTK format. However, I'm not sure if you can
put the geometry in a vtu file, the set of transient results in other vtu files
and assembly everything in a unique pvd file using wildcards.
