In this paper, we present some parallel performance results for a 3D simulator of coupled deformation, fluid flow and heat transfer in sedimentary basins. The model parameters are derived from an industry simulator, with realistic material properties and complex irregular grids of up to 1.5 million nodes with 7.3 million degrees of freedom. We have performed parallelisation on the linear algebra level using the ML algebraic multigrid preconditioner with iterative methods in the Diffpack finite element framework. Implementation and speedup results are presented.
