<font size=2 face=sans-serif><span style='font-size:10.0pt;font-family:sans-serif'>I
am working on a trnflow simulation (an apartment with passive stack exhausts),
and having some convergence problems. After looking at it I have found these
problems occur whenever the outside temperature gets significantly higher than
the interior temperature, as you can see in the attached image. Any suggestion
on how to deal with this?</span></font> <br>
