Project: A Framework for Multi-Physics Models

A Framework for Multi-Physics Models

Multi-Physics models involve coupling of different physical phenomena, often occuring in different parts of a global domain. In this project we want to develop numerical methods and software tools that make it easier to implement multi-physics simulators. The numerical approach is based on overlapping and non-overlapping domain decomposition methods, and the software approach utilizes object-oriented programming in a way that simulators developed for a single physical phenomenon (PDE) can be reused also in a coupled multi-domain context. An important point is to integrate parallel computing into the multi-physics framework.

Current activities in this project involve

flexible handling subgrids of a global grid,
applications to propagation of large, destructive flood waves (tsunamis) in the Pacific
