Hi, The problem is from Type 56. I have house with few rooms which are not rectangular, they are concave. So, I can’t make one room=one zone. I divided room on rectangles to make zones, and walls between zones of one room are VirtualSurface. Radiation is seemed OK, but air between two zones of one room isn’t mixed… What can I do? Is it possible to solve this problem in TRNBuild or I have to go outside Type 56 and operate in Simulation Studio? Regard, Karol |
