Overview
Functionality
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 1.12.0) 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
- Spatial Discretisation - High-Order Flux Reconstruction
- Temporal Discretisation - Explicit and Implicit (via Dual Time-Stepping)
- Precision - Single, Double
- Mesh Files Imported - Gmsh (.msh)
- Solution Files Exported - Unstructured VTK (.vtu, .pvtu)
Source Code
The source code is available on Github.
