FLEXI is a high-order numerical framework for solving PDEs, with a special focus on Computational Fluid Dynamics. FLEXI is based on the Discontinuous Galerkin Spectral Element Method (DGSEM), which allows for high-order of accuracy and fully unstructured hexahedral meshes. The solver is parallelized very efficiently for large-scale applications and scales to 500,000+ cores. Moreover, FLEXI comes with a capable pre- and post-processing suite that enables complex simulation setups up to the finished visualization.
FLEXI has been developed by the Numerics Research Group (NRG) founded by Prof. Claus-Dieter Munz and currently lead by Prof. Andrea Beck at the Institute of Aerodynamics and Gas Dynamics at the University of Stuttgart, Germany.
You can find detailed installation instructions, the extensive documentation and several tutorial cases for FLEXI here.
