Abstract: 

Multiphysics systems consist of more than one component governed by its own principle for evolution or equilibrium. As an example, we consider an agricultural land use scenario comprising a hydrology model and a biogeochemistry model. We employ the OpenPALM tool to realize a coupling scheme where the models run concurrently using an individual parallelization. Although the two models demand for very different computational effort to compute one time step, we achieve a balance by allocating appropriate computational resources for each of them. We assess the parallel performance of the coupled application in a 3D scenario. Our concurrent operator splitting scheme shows superior efficiency compared to common coupling approaches.
