Dear "COMIS" users: I am now trying to simulate the air-flow in an office building with an big atrium in the middle, with TRNSYS and COMIS. Because of the high...
dear Peng, I hope you can find mor detaild answar; I've been using comis in 2003-2004, to simulate a natural ventilated building with atrium to estract the...
Dear Xu Peng As mentioned by Marco, horizontal large openings are not included in COMIS (yet). I suggest to link the three atrium layers with normal crack...

Dear Viktor and Macro: Thanks for your kind help, but in COMIS 3.1 User guide, I've found the following instructions in "&-WI (Windows and Doors)" : Slanted...
... As I understand it, to model the atrium, you want to draw an imaginary plane at some height, and then use that plane as a division between two imaginary...

Dear David: Thanks very much for your detailed explanation that COMIS is not capable to deal with air flows that are dominantly caused by buoyancy effect...
Vince, ... COMIS has, or used to have, an input section called &-NET-ZL (zone layers). This section allows you to prescribe variations of temperature (and...

I am working on Coupling TRNSYS / COMIS, but I got some problems. I cannot get results( airflow) from comis. Is there anyone has similar experiences. I need...
Dear Ming, The best way to learn about coupled projects is to use the project wizard in the Simulation Studio graphical interface. Just select File/New and...
Thank for your help!but how to run the simulation as a TRNSYS stand-alone model £¿ thank you in advance Sincerely wangshuo Thank for your help!but how to...
Dear COMIS users, I am a beginner user of energy and airflow simulation programs. I studied theoretically how the different models works (in particular TRNSYS...
Hi Marcello, I'm not the top expert for the physics part of COMIS, so maybe someone else wants to add some information, but here is what I know: 1) Zoning...
Dear all, I have being using COMIS in 2004, and now I think I'm going to use EnergyPlus in a few months; as a doctorate student en LaSalle-URL university in...
Of course EPlus has a multizone airflow model, Macroflow....... I think Multizone airflow models are the same, nevertheless their own merits. For me, I would...

Dear members, I am a beginner user of TRNSYS/COMIS, and I am running my first simulations. I have a problem with COMIS that I do not understand. In fact, I...
Dear Marcello First, check your CIF with a COMIS stand allone run, but before define your desired the inside and outside conditions in the CIF. If this leads...
Dear Andreas, Thank you for the answer.I tried already to run the cif file alone, but results are of the same order of magnitude. I set an hour of simulation,...
Dear Marcello Now, I had a look into your CIF. The mistake is in the definition of your crack type and it's use in the link. If you want to define your crack...
Dear Andreas, thank you very much for your help! Actually, it was exactly that the problem. Now the model works proprerly! Best regards, Marcello To:...
