Abstract

The concentration equation in the model of miscible flow in porous media, such as appearing in reservoir engineering, is treated using unstructured finite volumes, implicit time stepping and domain decomposition. The computational effort can be demanding in particular in strongly heterogeneous reservoirs. A distributed parallel environment might be helpful here. We discuss some performance characteristics for an IBM-SP2. 1 Introduction Miscible flow in porous media can be conveniently modeled using unstructured finite volumes for the concentration equation in combination with mixed finite elements for pressure and velocity, see Consonni et al. [1], Fotia & Manzini [2] and Bergamaschi, Mantica & Saleri [3]. In reservoir e
