Abstract
The Freewake code from the DLR Institute of Flight Systems simulates the 3d flow around a rotor of a helicopter under active control. It is based on a vortex approach with models for special features of the rotor flow. The method is very well suited for massive parallelism, because the velocity needs to be accumulated independently for each node of the mesh. We will present porting of the existing MPI-parallel implementation to GPGPUs using OpenACC and analyze the performance of hybridly parallelized calculations on multicore CPUs with GPGPU accelerators.
