What is PyFR?

PyFR is an open-source Python based framework for solving advection-diffusion type problems on streaming architectures using the Flux Reconstruction approach of Huynh. The framework is designed to solve a range of governing systems on mixed unstructured grids containing various element types. It is also designed to target a range of hardware platforms via use of an in-built domain specific language derived from the Mako templating engine. The current release (PyFR 1.4.0) has the following capabilities:

  • Governing Equations - Euler, Navier Stokes
  • Dimensionality - 2D, 3D
  • Element Types - Triangles, Quadrilaterals, Hexahedra, Prisms, Tetrahedra, Pyramids
  • Platforms - CPU Clusters, Nvidia GPU Clusters, AMD GPU Clusters, Intel Xeon Phi Clusters
  • Spatial Discretisation - High-Order Flux Reconstruction
  • Temporal Discretisation - Explicit Runge-Kutta
  • Precision - Single, Double
  • Mesh Files Imported - Gmsh (.msh), CGNS (.cgns)
  • Solution Files Exported - Unstructured VTK (.vtu, .pvtu)
Who is Developing PyFR?

PyFR is being developed in the Vincent Lab, Department of Aeronautics, Imperial College London, UK. More details about the development team are available here.

Who is Funding PyFR?

Development of PyFR is supported by the Engineering and Physical Sciences Research Council, Innovate UK, the European Commission, BAE Systems, and Airbus. We are also grateful for hardware donations from Nvidia, Intel, and AMD.

PhD Position - The Impact of Boundary Representation and Mesh Quality on the Performance of High-Order Accurate Flow Solvers for Complex Aerodynamic Flows
Summary: A fully funded PhD position is currently available. The project, undertaken in collaboration with Airbus, will involve using the high-order flow solver PyFR to solve challenging flow problems in the vicinity of complex geometries. Candidates should hold, or expect to obtain, a 1st Class undergraduate degree in a numerate discipline from a world-leading university.
