When solving many partial differential equations (PDE), large linear(ised) systems of equations arise. For applications, particularly in 3D, direct solution methods are often prohibitive. Iterative methods provide a viable alternative, but usually an effective preconditioner is critical to obtain fast convergence. For many elliptic PDE efficient preconditioning methods are well established. For more general problems involving flow and/or wave propagation, the situation is less clear; however,significant progress has been made in the last few years. The speakers in this minisymposium will present theoretical underpinning as well as numerical results for preconditioning techniques applicable to these problems.
