MS4: Modeling and Numerical Methods for Coupled PDE Systems

Organizers: Xiaoming He, Missouri University of Science and Technology

                     Xiaofeng Yang, University of South Carolina

Abstract: Coupled PDE systems play a key role in many multi-physics problems.  The modeling and the subsequent development of efficient and stable numerical algorithms remain challenging for coupled PDEs due to a number of factors, including the nonlinear coupling of different dynamics, the multiple scales involved, and unconditionally stable high order methods.  This mini-symposium aims to provide a forum for researchers from different fields to discuss recent advances on the modeling and numerical methods for coupled PDE systems.
