Unstructured Algorithms for Inviscid and Viscous Flows Embedded in a Unified Solver Architecture: Flo3xx

This paper reports recent progress towards a new platform for computational aerodynamics on arbitrary meshes, tentatively designated Flo3xx. This tool is designed for maximum flixibility to serve as both an industrial strength flow solver on general grids, and as a framework for advanced research in the area of CFD and aerodynamic design. Such a flexible platform is crucial for transfering new research to industrial applications. We describe the capabilities and methods used in this tool, and show results from initial validation on inviscid and viscous testcases. Furthermore some open issues in CFD on unstructured grids will be addressed, such as viscous discretization and multigrid methods in an unstructured context.
