Abstract

In recent years, due to the increasing power of computers, it has become feasible to simulate fluid flows in complex geometries. This has introduced a new level of complexity in the field of Computational Fluid-Dynamics (CFD): users need to be able to describe much more complex computational spaces to flow solvers; for an efficient use of computational resources the computational domains have to be subdivided in possibly many sub-domains. Within each of these sub-domains the flow is then discretized depending on the flow solver used. The splitting of the computational domain is primarily done to maintain uniform precision in the computation, by creating smaller domains, and thus denser grids in the critical regions of the computational space. Moreover, one often has to consider a multi-domain computational space to be able to parallelize the code and/or use different flow solvers on different sub-domains.
