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 postprocessing suite that enables complex simulation setups up to the finished visualization.
