I will present in this seminar a sequential approach to accelerate immiscible multiphase flow modelling in heterogeneous porous media using discontinuous Galerkin methods and dynamic mesh coarsening. This approach involves dynamic domain decomposition and different solution strategies in the different flow regions, using a criterion that can be fastly evaluated. I will present a technique to estimate the position of the saturation front and identify the flow zones that need high-resolution gridding. The accuracy of the proposed approach is evaluated through test cases from the SPE10 model.
In the second part, I will briefly talk about my postdoc project on groundwater contaminations by nonaqueous phase liquids (NAPL), as part of the QUASPER project.
