FLEXI is a high-order numerical framework for solving PDEs, with a 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 and scales up to hundreds of thousand cores.
FLEXI has been developed by the Numerics Research Group (NRG) lead by Prof. Claus-Dieter Munz at the Institute of Aerodynamics and Gasdynamics at the University of Stuttgart, Germany.
This is a scientific project. If you use FLEXI for publications or presentations in science, please support the project by citing our publications given in references.
