Multi-physics simulations are at the heart of today's engineering applications. The trend is towards more realistic and detailed simulations, which demand highly resolved spatial and temporal scales of various physical mechanisms to solve engineering problems in a reasonable amount of time. As a consequence, numerical codes need to run efficiently on high-performance computers. Therefore, the framework Zonal Flow Solver (ZFS) featuring lattice-Boltzmann, finite-volume, discontinuous Galerkin, level set and Lagrange solvers has been developed. The solvers can be combined to simulate, e.g. quasi-incompressible and compressible flow, aeroacoustics, moving boundaries and particle dynamics. In this manuscript, the multi-physics implementation of the coupling mechanisms are presented. The parallelisation approach, the involved solvers and their scalability on state-of-the-art heterogeneous high-performance computers are discussed. Various multi-physics applications complement the discussion. The results show ZFS to be a highly efficient and flexible multi-purpose tool that can be used to solve varying classes of coupled problems.

Zonal Flow Solver (ZFS):一种高效的多物理场仿真框架

多物理场仿真是当今工程应用的核心。趋势是朝着更真实和更详细的模拟发展,这需要高度解析的各种物理机制的空间和时间尺度,以在合理的时间内解决工程问题。因此,数字代码需要在高性能计算机上高效运行。因此,已经开发了具有格子玻尔兹曼、有限体积、不连续伽辽金、水平集和拉格朗日求解器的框架分区流求解器(ZFS)。求解器可以组合起来模拟,例如,准不可压缩和可压缩流动、空气声学、移动边界和粒子动力学。在这份手稿中,介绍了耦合机制的多物理场实现。并行化方法,讨论了所涉及的求解器及其在最先进的异构高性能计算机上的可扩展性。各种多物理场应用补充了讨论。结果表明,ZFS 是一种高效且灵活的多用途工具,可用于解决各种类型的耦合问题。
