When we run a time-dependent problem, the solution might "move around",

do people do with such problem?
Many of the GridRefinement functions allow you to specify an upper bound
for the number of cells they produce. Alternatively, you can cap the
level of refinement -- that's what step-26 and 32 do, for example.
