FLEXI is a high-order discontinuous Galerkin (DG) simulation code for the solution of the time-dependent compressible Navier-Stokes equations on unstructured hexahedral elements in three space dimensions. The code was specifically designed for very high order accurate simulations on massively parallel systems. It is licensed under GPLv3, written in Fortran and parallelized with MPI.
