“…They can generally be classified into two categories; highlevel execution managers that coordinate the execution of standalone legacy codes, and low-level frameworks that provide a common data format and communication protocol from which the higher-level executable may be built. Examples of the former include FD-CADRE 28 and MDICE, 14 which are used to manage execution of different codes for multidisciplinary overset moving-body problems. Each code is run in a standalone fashion, maintaining its own parallel implementation and exchange data through file I/O.…”

This paper describes a computational infrastructure that supports Chimera-based interfacing of different CFD solvers-a body-fitted unstructured grid solver with a blockstructured adaptive cartesian grid solver-to perform time-dependent adaptive movingbody CFD calculations of external aerodynamics. The goal of this infrastructure is to facilitate the use of different solvers in different parts of the computational domain-body fitted unstructured to capture viscous near-wall effects, and cartesian adaptive mesh refinement to capture effects away from the wall. The computational infrastructure, written using Python, orchestrates execution of the different solvers and coordinates data exchanges between them, controlling the overall time integration scheme. Details about the infrastructure used to integrate the codes, the parallel implementation, and results from demonstration calculations are presented.

The present work is investigating the vortex dominated flow physics as well as the aerodynamic behavior of swept wing configurations with round leading edges. The research is based on numerical simulations using the CFD method DLR TAU. The target configurations are swept wings of constant aspect ratio, variable leading edge contours and leading edge sweep angles. The work is dealing with the onset of the vortical flow at the leading edge for constant and variable leading edge nose radii, the influence of the angle of attack, the leading edge sweep and the onflow Mach number. Furthermore, the aerodynamic behavior is analyzed and assessed as well as the specific flow physics in the vicinity of the vortical flow separation at round leading edges. The objective of the present work is to provide a contribution for the design and assessment of the physical characteristics of swept wing configurations. Furthermore, sensitivities will be given for the design process. In addition, the current investigations provide a deeper understanding of the separation onset process and the flow physics of swept wing configurations with round leading edges.
