NSU3D (Navier-Stokes Unstructured 3D)

is a state-of-the-art Reynolds-Averaged Navier Stokes code based on unstructured meshes. The solution algorithms in NSU3D have been in continuous development and validation for more than 20 years, providing accurate, reliable and repeatable results over a wide range of flow regimes. Fully unstructured mesh support with automatic hybridization of tetrahedral meshes greatly reduces meshing overhead while automatic agglomeration multigrid and line implicit solution in the near wall regions provide rapid results on large models.
