Mini-symposium (MS)

MS3: Recent Advances in Numerical Methods for PDEs

Organizers: S.S. Ravindran, University of Alabama in Huntsville

Abstract: The rapid growth and diversity of research in science and engineering over the past decades has spawned many intellectually challenging and computationally intensive PDE problems to be solved.  Despite significant progress made in development of efficient computational methods for numerical solution of these problems, many problems still remain open.

This minisymposium aims to provide a platform to present recent developments on the novel and efficient numerical methods for solving PDEs, enable in-depth discussions on a variety of computational efforts for solving problems arising in areas of science and engineering from researchers at all stages of their careers.
