DISCRETE GREEN-FUNCTIONS AND HYBRID MODELING OF THERMAL AND PARTICLE DIFFUSION

This paper provides details of a widely applicable technique of hybrid modelling of thermal and particle diffusion which can help to reduce computational load in explicit formulations. The undersirable effects of artificial boundaries, which are introduced when a simulation is tr uncated or when an expanding mesh is used, can be eliminated by the us e of discrete Green's functions. The technique can also be applied to problems involving infinite or near-infinite domains or problems where a complex thermal region is embedded within a larger, more simply des cribed domain.
