ConMan is a finite element program for the solution of the equations of incompressible, infinite-Prandtl number convection in two dimensions, originally written by Scott King, Arthur Raefsky, and Brad Hager.
ConMan is a public domain program and is distributed free of charge to anyone who wishes to use it, and may be freely copied and modified. ConMan is written in Standard Fortran 77 with cray pointers and runs on most UNIX systems with many Fortran compilers. Porting it to other systems should be straightforward. As with anything free, ConMan comes with no guarantees, but it has been benchmarked against other existing codes.
