Distributed implicit stepping with unstructured finite volumes for 2D-transport

A detailed description of transport phenomena in real-life complex geometries is important in several areas of reservoir and environmental engineering. This paper presents numerical issues related to the application of high-performance computing in this field. The specific example treated comes from reservoir engineering. A distributed parallel environment is developed based upon domain decomposition. We discuss both the iterative properties and the parallel performance on an IBM-SP2. It will be shown that the numerical approach leads to an attractive tool for treating real-life large-scale problems.
