Abstract/Summary The solution of transport problems is a key component for most numerical simulations in Geosciences, for instance in mineralization, CO2 sequestration and ground water flow. Characteristic features of these transport problems are large jumps in material coefficients, in particular through changes in rock porosity. In the paper we present a general framework for solving a general type of transport problems using an operator splitting approach and algebraic upwinding with flux correction. We will test the proposed framework for a typical problem arising from modelling mineralization in a sedimentary structure. The tests indicate that the backward Euler scheme with flux correction has the potential of providing transport solver for Geoscience applications which is weakly scalable for practical scenarios.
