Would the same work for non-structured problems, for instance for power flow
equations?
Thx. Domenico Lahaye.

Suppose I have a problem for which the field variable has multiple components,

that makes this “easier?”
DMDA knows about components so that MatStencil has a .c slot for indices. Is
that what you mean?
Thanks,
