Dear all, Best wishes for 2006! Does anyone have a list of CER messages? This would be very helpful.. Second, does anyone know what this error means: ***CER***...
Dear Jagdeesh, You seem a bit lost. Let me give you some guidelines It is quite clear that you have no idea 1) about the context of your project (Airflow in...

Dear all, I have a flow controller which has a dip in its curve. How should i model this in comis? Thehe dip results in a negative pressure link. I can...
Dear All, I need to read 2 data calculated in TRNSYS, to export them as Inputs in an Excel file and to save this Excel file as a text file (filename.txt),...
Dear Berangere, If I understand your problem well, you should simply prevent XLS to ask you if you want to overwrite an existing file... Have a look to the...
That's right, TRNSYS Type 62 only executes the Visual Basic (VBA) code contained in the .xls file. If you continue to have problems with this, you might rather...
I am just starting to use Comis and trying to get grips with how it works. I am running a test case situation of a two-roomed building with no stack effects,...

Hello dear COMIS team... In order to calculate the CO2 emission of an occupant, you must specify his sex, age, height, mass and metabolic rate, as well as his...
Can anybody explain to me further how the calculation of airflow thought windows/doors LVO type 1 is performed? Are there any diagrams, other than figures 4.7...
Dear Andrew The mathematical description of LVOs is given in the attachment. Width and height factor define the fraction of the total width and height which is...
Thank you for the response, but I think I figured most of the details out myself by running a battery of simulations and investigating the results. However, it...
Andrew, The list is configuered not to store file attachments per default, that's why it disappeared. I uploaded Andrea's document to the 'Files' section of...
Dear all I have a model in trnflow in which I control fans through CO2- concentration: when czone(CO2)>1100 a fan switches on and increases its flow (fanspeed...
Dear all: I've just learned COMIS.As for multizone model, I wonder is there any differences in the principles which are adopted in COMIS and CONTAMW? Thank...
... COMIS and CONTAM both implement the same basic airflow physics. CONTAM has a nice feature to simulate transport delay in ducts, if that's important to you....

Hi, Dave Thank you for your help. I've read your paper "Computational Aspects of Nodal Multizone Airflow Systems," and I still cannot figure out the...
... Everything the paper describes is absolutely identical between CONTAM and COMIS. Both of them use that basic framework for representing and solving the...

Dear all: I've just learned COMIS As for multizone model. I¡¯ve used TRNSYS 16 some times and heard that TRNSYS could be couple with COMIS. I wonder how to...
Dear one, TRNSYS 16.1 will contain a special 'coupled project template' that you can use to easily create coupled projects. It creates a TRNSYS project which ...
Yes, I would try it. could you send me a beta version? And I wonder how to install this software. Does it work with TRNSYS 16.0 or not? thanks xi.wang ... you...
Yes, the beta does work with TRNSYS 16.0. Please send your user.id to software@... (not to the list), and we will provide an installer for you. Werner ... ...
HI, I don't know what's your means? what's the user.id? I've just send a mail to software@....with the user.id of the yahoo. it is ok? and that the installer...
Is there a way to force COMIS to fix the pressure at an external facade element to a specified value? I am running comparison studies and I only have...
Dear Andrew, Can't you just calculate your wind velocity from Delta P = 0.5*Cp*rho*v^2 ? You have P(t), Cp (tabel/calculator) and rho, so you could feed comis...
Hi Andrew, You can use the "constant pressure" external node (under "External nodes" in the component tree in the COMIS Simulation Studio). If you are writing...
