For steady problems, the time is a fictitious term and you march in time until the solution has converged. Look for papers by Kwak ( you may find it in NASA repositories too).

Dear ztdep,

Using the 'Penalty Method' is a nice, simple way to perform 'almost-incompressible' fluid flow calculations - marching forwards in time.

Take a look at the <www.freefem.org> site I mentioned in another message, or try the site <www.adthermtech.com/wordpress3> for some papers mentioning use of this method.

Regards, mw...
