Coupled Fluid-Particle-Scalar simulation of material transport in water. Based on waLBerla (massively parallel LBM framework for multiphysics applications) coupled with a parallel rigid particle dynamics (RPD) simulation and solver for the convection-diffusion equation for scalar transport. Aided by code-generation technologies lbmpy and pystencils and surrogate assistance.
Used by CoE: HiDALGO2
Main uses: Simulation of pollutant transport in aquatic environments, addressing pollution from microplastics, chemical- or temperature contaminants on newest HPC technologies.
