condition</title></head><body>
<div>Has anyone implemented a permeable bottom boundary condition for
any of the CitCom codes? I know how to do this in 2-D stream function
but I have not tried it in 3-D? That is,fluid exits the domain
perpendicular to the boundary, comes in at a given temperature, and
the boundary does no work on the domain of calculations.</div>
<div><br></div>
<div>If not, is there another public source code that does this?</div>
