FLEXI/GALÆXI: Open-Source Solver for Multiscale Flows

October 30 @ 11:00 am – 12:00 pm

A promotional graphic for the CASTIEL code of the month "FLEXI/GALÆXI: Open-Source Solver for Multiscale Flows." The text includes "Code of the Month Vol. 11, October 30th, 2024" and "Speakers: Anna Schwarz, Centre of Excellence in Exascale CFD (CEEC)." The background features an abstract design with a large circle on the left, displaying a gradient of colors from blue to orange, suggesting multiscale flows. The bottom right corner displays the words "FLEXI GALÆXI" in bold letters.

Join us for the 11th CASTIEL Code of the Month to learn about FLEXI/GALÆXI!

In the field of computational fluid dynamics (CFD), high-order methods have reached a certain level of maturity for the solution of unsteady multiscale problems, of which turbulence is a prime example. For these types of problems, high-order schemes have proven to be efficient alternatives to more traditional numerical schemes. Among the high-order discretization variants, the discontinuous Galerkin method offers a collection of features which increased its popularity. In order to take full advantage of the potential benefits of these methods, all steps in the simulation chain, from pre- to post-processing, must be designed and executed with high-order in mind.
In this talk, we will present the open-source CFD frameworks FLEXI/GALÆXI, which are continuously developed by the Numerics Research Group of Prof. Andrea Beck at the Institute of Aerodynamics and Gas Dynamics at the University of Stuttgart. Both solvers provide a high-order consistent simulation tool chain for solving the compressible Navier–Stokes equations in a highly efficient, accurate and robust manner in a high performance computing setting either on CPU-based systems (FLEXI) or GPUaccelerated clusters (GALÆXI). The talk commences with a description of the numerical algorithms and implementation details, accompanied by an outline of the features and capabilities of all parts of the framework. In addition to these technical details, we also discuss the significant issues of code stability, reproducibility and user-friendliness. The advantages gained by developing an open-source framework are addressed, with a particular focus on usability for the open-source community. We conclude with application examples that demonstrate the wide range of use cases and the extensibility of FLEXI, as well as an overview of current and future developments.
