[vtkusers] file format for transient analysis

[Hom Nath Gharti]

Ensight GOLD format is one of the formats that you may want to look.  In
which defining both a constant geometry as you mentioned or a variable
geometry is possible.

Look chapter 11 at

<http://www2.ensight.com/91_manuals/UserManual.pdf>for detail.

Good luck.
