NSU3D is a package for computing steady-state aerodynamic flows over arbitrary configurations using unstructured meshes. Mixed element unstructured meshes containing arbitrary distributions of tetrahedra, prisms, pyramids and hexahedra can be handled. The Reynolds-averaged Navier- Stokes equations are solved including the solution of turbulence modeling equation(s) to simulate turbulence effects.
The solver relies on an unstructured (agglomeration) multigrid procedure to accelerate convergence to steady-state, while maintaining relatively low memory requirements. The solver generally requires 200 words or 1.6 Kbytes (in double precision) of memory per grid point. The solver is vectorizable and parallelizable using the OpenMP parallelization directives and/or the MPI message-passing library.
