If you write a solution multiple times to the same file, you should get 
a time series that you can plot in Paraview (by pressing the play button 
or stepping):

Function u;
File file("solution.pvd");

file << u;
// Do something with u
file << u;
// Do something with u
file << u;

etc.

(If naming is a problem, call the rename() function on u:

u.rename("u1", "some description");)
