Domain decomposition is a very successful strategy for solving boundary value problems in parallel on supercomputers. The basic idea is to partition the grid of the domain into many small subdomains, and to solve boundary value problems on these small subdomains in parallel. Boundary value problems are used to model many natural phenomena, for example the flow of a fluid through a porous medium such as sand. If the medium consists of a mixture of several different materials, the rate at which the fluid flows will vary greatly across the domain. In this talk, we will discuss how we can design domain decomposition methods that work well for boundary value problems with heterogeneous diffusivity.
