Abstract

We present a software for the hybrid parallel calculation of rotor forces and control angles using a coupled simulation of rotor dynamics and rotor wake. A big part of the computation time is required to simulate the airflow in the wake using a vortex method. For node-level parallelization, we use OpenACC on GPUs and OpenMP on CPUs, and MPI for parallelization between compute nodes. We focus on the coupling scheme and discuss the performance obtained.
