The development of faster algorithms for solving practical applications in science and engineering is paramount for the simulation of physical phenomena investigated nowadays. We will focus on finite element discretization of PDE models that have a mixed or/and a saddle point variational formulation such as fluid flow and electromagnetic models. We plan to bring together researchers representing the most recent advances in mixed and saddle point methods for solving variational problems. The proposed approximation techniques include development of fast preconditioners and robust iterative solvers.
