Piet Jarmatz: Coupling the Lattice Boltzmann Software Walberla and Molecular Dynamics Simulations Using the Macro-Micro-Coupling Tool

Multiscale simulations in computational fluid dynamics often require a huge amount of computational power. In this talk a spatially adaptive, massively parallel coupled Lattice Boltzmann / molecular dynamics simulation using the highly efficient LB C++ Framework 'waLBerla' from Erlangen is presented. The modular implementation with the Macro-Micro-Coupling tool, different interfaces and the generic base data structures make it flexible and usable for many applications. A standardized three-dimensional channel flow scenario is used to validate the coupling and evaluate the performance on the MAC cluster.
