Why do we need HMM?

Dr. Weinan E

Abstract:   There has been a long history of multiscale methods that capture the macroscopic behavior of systems using directly the microscopic models, without using any explicit macroscopic models. Examples include the Car-Parrinello method (1985), Gas-kinetic scheme (1994), Quasi-continuum method (1996) and gap-tooth scheme (2002, unpublished). Why, on top of these, do we still need yet another multiscale method, the heterogeneous multiscale method (HMM)? We will address this question from several different angles. In the second half of the talk, we will present applications of HMM to interface problems.
