Re: [EnergyPlus_Support] natural convection
If the only connection specified between the two zones is a surface, then there
is no airflow between them. The ActiveTrombeWall.idf example file illustrates
one approach to moving air between two spaces. MIXING and CROSS MIXING objects
can also be used. To model buoyancy-driven flows between the two zones would
require the use of the COMIS air flow model.
