NASA的CFD计算流体力学软件，功能强大，用途广，可用于科研和实际工程计算。 源代码，已开源，可用于科研((CFL3D is a structured-grid, cell-centered, upwind-biased, Reynolds-averaged Navier-Stokes (RANS) code. It can be run in parallel on multiple grid zones with point-matched, patched, overset, or embedded connectivities. Both multigrid and mesh sequencing are available in time-accurate or steady-state modes. 2-D or 3-D grid topologies Inviscid, laminar, and/or turbulent flows Steady or unsteady (including moving-grid) flows Multiple block options: 1-1 blocking patching overlapping embedding Convergence acceleration options: multigrid mesh sequencing Turbulence model options: Baldwin-Lomax Baldwin-Lomax with Degani-Schiff Modification Baldwin-Barth Spalart-Allmaras (including DES option) Wilcox k-omega Menter's k-omega SST Abid k-epsilon Explicit Algebraic Stress Model (EASM) k-epsilon and k-omega variations K-enstrophy Reynolds stress model))
