Dear firedrakers, Can we have a discussion about the "R" space (function space of global constants), which if I understand correctly has not been implemented?
R is useful for things other than boundary conditions, too. If you have a constrained optimisation problem with a single constraint (an integral constraint, say, like [0]), you'll need R to write down the associated KKT system. I don't see how that would be possible with passing nullspaces to Krylov solvers. (Please enlighten me if someone here does know how.) Some problems really just do have a global coupling through a single real. (I also completely understand that its implementation is a pain) Patrick [0] 10.1002/fld.426
