大型CFD源程序DUNS，求威望 介绍： Diagonalized ADI Navier-Stokes (DUNS) Code The DUNS code is a 2d/3d, structured, multi-block, multi-species, unsteady or steady, 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. It is written in FORTRAN-77 and C. It has been used primarily as a research code, and because of that, the coding can be at times rather undocumented and unclear.(Large-scale CFD source DUNS, seeking prestige Introduction: Diagonalized ADI Navier-Stokes (DUNS) CodeThe DUNS code is a 2d/3d, structured, multi-block, multi-species, unsteady or steady, Navier Stokes fluid dynamics code with the q- omega turbulence model.
