[pooma-dev] Cooperation between FieldStencil and Range?

[James Crotinger]

The problem is that one can not, in general, deduce geometry information on
a red-black type subgrid from the information on the underlying grid. Thus
only Interval views of a Field yield a Field with geometry information. RB
type calculations can be done on arrays, so you might want to change some of
the calculations to be array-centric.
