Hi Knut Erik<br>
<br>
It looks like this is the main question remaining on your greenhouse
simulation.<br>
<br>
I would set convection coefficients to zero (or a very small number if
zero isn't accepted), and us a separate method to define the air
exchange between the two zones with a coupling when the screen is
open. The large direct air exchange between the zones renders any
convection coefficient meaningless.<br>
<br>
Regards<br>
Erik<br>
