I have an application where I need to solve three nearly identical systems. For each system, the matrix entries and the rhs will be slightly different, but the mesh and finite element type and degree will be identical. I have three questions: 1) I would like to reuse the DofMap between each of these systems to save memory (and any other memory that is possible, I am not sure what the overhead per system is); 2) if it is not convenient to avoid duplication of the map memory, I would like to construct the system such that at least the three maps are the same (will this happen automatically?); 3) can I specify an initial guess for the solution when using an iterative solver so that I can use the solution of one system as the initial guess for the another.
