I like this because we are using DM for our equation abstraction. I think the dependency loops are due to refusal to decompose the DM.

What do you mean by "decompose the DM"?

Right now, DMs wrap up - Domain Topology - Domain Geometry - Modeling approximation (like function spaces, projectors) - Modeling equations (including decompositions, variable substitutions) and I may have forgotten some stuff. That is a huge amount of crap for one object.
