Abstract: We describe a numerical algorithm for gas dynamics simulation in rotor–stator systems based on sliding meshes and edge-based schemes. Multilevel MPI+OpenMP parallelization for cluster systems is described in detail. Parallel efficiency has been demonstrated on up to 1400 cores, as well as on Intel Xeon Phi accelerators. The scheme is verified by solving acoustic problems. Robustness of the algorithm is demonstrated on simulation of a model ventilator.
Keywords: edge-based scheme, unstructured mesh, rotor–stator, MPI, OpenMP.
