The aim of this project is to develop fast linear solvers for
heterogeneous saddle point problems as appearing during the iterative solution of non-smooth
optimization problems, e.g., in the context of phase field models. While the development of nonlinear solvers for phase field models has reached a certain maturity, the existing solvers for the linear subproblems are still unsatisfactory. As a first step, we
focus on two-phase models. Later, we plan to extend these solvers for multiphase systems.
