[TRNSYS-users] Cross flow ventilation

[Loic Tachon]

Dear Trnsys community,

I want to simulate the stack effect in a high room with high thermal gain.

For this, I have 1 zone and 5 thermal air nodes in the z direction to get
the temperature at several heights.

How can I do this and avoid that TRNSYS see ceiling between the zone ? Do I
need to delete the horizontal surface for zone 2-3-4 ? Or do I put mass
less horizontal surface ?

As Well, how do I do the cross flow ventilation ? Do I use the couple mass
flow between zones ?

 or I put a coupling air flow (same that natural ventilation mass flow) for
the horizontal surface ?

Thanks a lot.

Best regards,
