NaSt2D

This is a computer code for the solution of the 2D, incompressible Navier-Stokes equations. Basic features are

• Chorin's projection method for momentum/continuity decoupling
• Staggered mesh for spatial discretization
• explicit Euler scheme for time discretization
• blending of first order upwind and second order central discretization for convective terms
• SOR iterative solver
• can handle very complicated geometries by a simple cell decomposition/enumeration technique

Gordon Cichon wrote an interactive wrapper for an older version of NaSt2D with a nice graphical interface runing under LINUX. You can get it from here.
