Numerical diffusion induced grain boundary motion and methods for evolving interfaces

Tuesday 21st January 2003 - 10:00 to 11:00
INI Seminar Room 1
Session Title: 
Mathematical Challenges in Scientific and Engineering Computation
In this talk we describe applications involving curvature dependent interface motion and approaches to numerical approximation. In particular we consider grain boundary motion in thin metallic films induced by diffusion of atoms from a vapour. Three numerical approaches are introduced:1)Direct approximation of the sharp interface equations, 2)Phase field approximations and 3)Level set formulations.
