Pasha, there are tutorial programs, such as step-22[1], that use BlockMatrices and solve for individual blocks. What exactly is the problem you are facing? Does it have anything to do with Trilinos objects or is it a conceptual problem?
Can you tell us how exactly you want to split solving your system?
