I am about to debug our incompressible flow solver (finite volumes on a staggered grid; pressure correction, cartesian grid). Therefore it would be helpful to have a similar code in order to interchange the different parts of the solver.

Any information about freely available code of this type is highly appreciated.

The codes made available by M. Peric look exactly like what you are looking for. Ftp ftp.springer.de login: ftp passwd: your E-mail address cd pub/technik/peric get read.me and read this file to proceed further
