In this paper, a cross-section of numerical algorithm development at NLR for end-user applications in aerospace is presented. Aerospace is characterized by high safety requirements and standards, complex development programs and operational processes, and challenging multi-physics phenomena. An example is the certification or qualification of...

The simulation of certain time-dependent flow phenomena can pose a grand challenge to Computational Fluid Dynamics. In this paper, a multitime multigrid convergence acceleration algorithm is introduced which significantly reduces the turnaround time to reach time-periodic solutions. The application of this convergence acceleration algorithm will...
