r-values of airgaps
 

Hello,

posted similar in the ANSYS world, my trouble is I want to model air gaps like in a stud wall or in a double glazed window. Different temperatures both sides. Is there some software to do so, either just the losses/gains or better still what kind of air movement will happen? Its pretty much natural convection? Comsol is a bit of a pain too, it seems...

Regards,

Steffen.
