Hi everyone,I'm still encountering the same problem about ventilation in my project. I've set all the ventilation network, and then I closed all the windows. There is no heating device in the building.
I don't understand why, but at around 749 hours, I encounter this error: COMIS MESSAGE ***** ERROR ***** Flow matrix is singular ! This might be caused by a zone that has no ventilation at all in this condition. Age of air and air change efficiency output is invalid !And this occurs until the end of the simulation, though the simulation runs until the end. I only found that when I opened the .cer file.
Moreover, when I put a heating device in a room, with limited power, the simulation stops before the end, saying that convergence was not reached. Do you think this is related to the COMIS ERROR I showed just before?
If someone can help me, I attach all my project to this mail, with an illustration, in order to better understant what I did. I used TRNSYS17.
