PyFR v2: Towards Industrial Adoption of Scale-Resolving Simulations
Freddie Witherden · 2024
High-order numerical methods for unstructured grids combine the superior accuracy of high-order spectral or finite difference methods with the geometrical flexibility of low-order finite volume or finite element schemes. The Flux Reconstruction (FR) approach unifies various high-order schemes for unstructured grids within a single framework. Additionally, the FR approach exhibits a significant degree of element locality, and is thus able to run efficiently on modern many-core hardware platforms, such as graphics processing units. Consequently, FR offers a promising route to performing affordable, and hence industrially relevant, scale-resolving simulations of hitherto intractable unsteady flows within the vicinity of real-world engineering geometries. In this talk we will describe the functionality new to PyFR v2.1. Performance and scaling numbers will be presented on a variety of platforms along with a demonstration of our state-of-the-art shock capturing technology. A brief review of the history of PyFR since its inception in 2012 will also be provided.
