Abstract

In flow and non-reactive transport problems, an efficient division of labor for a parallel computer is given by a decomposition of the domain that assigns roughly an equal number of grid cells to each processor. Typical geochemi- cally reactive transport problems exhibit reaction fronts or zones that travel through the domain and may be concentrated near heterogeneities in the domain, such as wells or sources of contaminants. Within these fronts, ki- netic reactions may be governed by relatively stiff differential equations. and equilibrium reactions may be near poorly conditioned minima in the Gibbs free energy. Thus the geochemical computational workload can vary greatly with po
