[TRNSYS-users] problem of convergence

[Yujun TAO]

Hello,
I have a problem of convergence when i simulated a complex building with double skin ventilated. I found when the window "adjacent" has a big surface like 60m² in zone "DPSE", the simulation took many times and is difficult to converge. When the surface reduced like just has 10m², the simulation goes fast and has no problem of convergence. But the window should have 78m² in the reality. 
So how could I resolve this problem? 
Sorry the files bui and tpf couldn't be attached with mail, blocked by the firewall of yahoo.
