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.

Examples of using PyFR are available in the examples directory. Currently available examples are:

• 2D Couette flow
• 2D Euler vortex
• 2D incompressible cylinder flow
