Hi,
It's been a while since I used InterGridMap so I forget the answer to
this question - the doc states:
"This class provides a map between two grids which are derived from the
same coarse grid."
Now, what is meant by "the same coarse grid"? Could, say, the two
Triangulation objects corresponding to the two DoFHandlers be completely
independent, as long as they have originated from two coarse grids that
have the same dimensions and grid spacing?
i.e. would integrid_map below behave as i think it should:
Triangulation<2> tria1;
Triangulation<2> tria2;
DoFHandler<2> dof1;
DoFHandler<2> dof2;
dof1 (tria1);
dof2 (tria2);
GridGenerator::subdivided_hyper_rectangle(tria1, divisions, p1, p2);
GridGenerator::subdivided_hyper_rectangle(tria2, divisions, p1, p2);
... [adaptive refinement on both grids, independent of one another]
InterGridMap<DoFHandler<2> > intergrid_map;
intergrid_map.make_mapping (dof1, dof2);
