It was added to UFC to allow a form compiler to precompute the dofmap
by iterating over the mesh. If you look at DofMap.cpp in DOLFIN you
will see this:
// Initialize UFC dof map
const bool init_cells = dofmap.init_mesh(ufc_mesh);
if (init_cells)
{
UFCCell ufc_cell(dolfin_mesh);
for (CellIterator cell(dolfin_mesh); !cell.end(); ++cell)
{
ufc_cell.update(*cell);
dofmap.init_cell(ufc_mesh, ufc_cell);
}
dofmap.init_cell_finalize();
}
init_cell and init_cell_finalize are not used by FFC only SyFi so
init_mesh should return false and the other two should be empty.
We probably need something like
format["do_nothing"] --> "// Do nothing"
in the format dictionary.
