External Aircraft Aerodynamics

UC1 simulates steady airflow at transonic speed and computes typical characteristics such as air velocity and direction, pressure and turbulence via the CODA CFD software and the FlowSimulator framework.

UC1 is dedicated to the high-fidelity numerical simulation of turbulent flows around complex aircraft configurations at high Reynolds numbers on unstructured grids. It solves the Reynolds-averaged Navier-Stokes equations (RANS) with a Spalart-Allmaras turbulence model (SA-neg). It uses finite-volume discretization on unstructured grids to allow for high accuracy, especially, in the boundary layer. The use case is designed to evaluate performance and scalability on current and upcoming HPC systems by using a hybrid MPI/GASPI and OpenMP parallelization and the inclusion of hardware accelerators such as GPUs.
