Compatibility List

The DUNS code is a 2d/3d, structured, multi-block, multi-species, steady or unsteady, Navier-Stokes fluid dynamics code with the q-omega turbulence model. It is configurable on several different levels allowing you to make the code as general or as efficient as you desire. It has been developed on Linux, Cray, RISC6000 and to a lesser extent SGI and HP architectures and is written in FORTRAN-77 and C. The current code is hosted by sourceforge at http://sourceforge.net/projects/duns/.
