Abstract Classic hybrid computational fluid dynamics ‐ computational aeroacoustics simulations rely on disk I/O to exchange large volumes of data between the flow solver and the aeroacoustics solver, which considerably limits the scalability of the overall scheme. A direct‐hybrid method is presented that eliminates this restriction by executing both solvers simultaneously on a joint hierarchical Cartesian mesh. Simulation results for a pair of co‐rotating vortices show the parallel efficiency of the approach. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
