SUMMARY:Simulation of Multiphysics Applications Using Hierarchical Cartesi
an Meshes and Dynamic Load Balancing
DESCRIPTION:Minisymposium\n\nSimulation of Multiphysics Applications Using
Hierarchical Cartesian Meshes and Dynamic Load Balancing\n\nMeinke, Niemo
eller, Herff, Satcunanathan, Lintermann...\n\nThe computational methods, t
heir HPC implementation and recent results of various large scale engineer
ing multiphysics applications will be presented in this paper. The computa
tional method is based on a unified hierarchical Cartesian mesh with an im
mersed boundary formulation, ideally suited for the prediction of flows wi
th embedded moving bodies. Since the computational load changes dynamicall
y on the individual subdomains due to the various physics and moving surfa
ces, a dynamic load balancing strategy based on the computational time is
used to achieve a high parallel efficiency. Details of the implementation
will be summarized in the presentation and its performance will be demonst
rated in large scale engineering examples, such as the noise reduction by
porous media, turbulent combustion problems and multiphase flows. The perf
ormance of the dynamic load balancing strategy will be demonstrated, e.g.
for coupled fluid mechanics and aero-acoustic predictions.
