Hello, experts As my project has lots of zones, the current screen of COMIS3.2 (simulation studio)has limited screen to hold all of icons. How can I enlarge...
Hi Justin, File/Settings does the trick: choose the 'Project' tab and edit Height and Width in the 'Project size' frame. However, this only works for newly...
I am working on coupling Comis with Type 56 Of TRNSYS. I Developed comis airflow model and thermal Type 56 model separately, And they work Very well...
Dear all, For my first coupling simulation, I want to calculate the CO2 concentration in a classroom, but I encounter some difficulties. When I run the...
This error means that your project is too complicated for the demo version. If you cannot simplify it, you have to buy the full version to run it. If you have...
Dear Thomas, When adding COMIS as type 157 to a TRNSYS project, you basically redefine all variables which are inputs to type 157: as these are now computed by...
Hi, Werner Thanks your reply. I tried to find the file/settings, but I cannot find it in my simulation stuio 2005, which is comis standalone version. Do you...
Justin, This function has been in all versions of Simulation Studio since the beginning. Please look at the attached picture to try to locate it. Werner ...
Hi Werner, Thanks for your help. As you tell me, I simplified my model and I have now a elementary model with a single type 157, with different schedules for...
I'm not at the office right now, but maybe you can send your simplified project to the list and someone else can take a look? (If not, I may have time to look...
I just tried to look at your files, but as far as I can see it contains only the TRNSYS part. The air flow model (.cif / .cpf files) are not in the Zip. (This...
Indeed, I made a mistake. I put the files again. Thomas ... contains only the TRNSYS part. The air flow model (.cif / .cpf files) are not in the Zip. (This may...
Dear all, I was confused that there were still flow rate and pressure in zones even if I set wind speed zero and no temperature difference between inside and...
Dear Comis users, I am doing some calculations to estimate the potential of cooling by natural ventilation during mid seasons in offices. I have some orders of...
Hi Marcello, If you supply 0.1 m/s through the floor (as experiment in your mind) that would lead to about 133 ACH if the room is 2.7 m high. So 28 is possible...
According to my (limited) knowledge, and in absence of an answer by the experts, phenomena causing air flow in COMIS include - wind pressure (meteo data in...
Hi all, Currently, I got a big problem with coupling TRNSYS and COMIS. Is there anyone familiar with integration with TRNSYS and COMIS? I hope someone can help...
Dear Ming, To use the coupling, you should simply create a new project in Simulation Studio, and choose File/New ... Then select 'Coupled project'. This will...
Hi all, Currently, I am trying to solve a big problem about integration with TRNSYS and COMIS. I am supposed to get two kinds of result: temperature and...
Dear TRNSYS and COMIS users, I cannot get cos-files with Type 157. I attach the files of coupled project created with the wizard of Simulation Studio. It is a...
Dear Ken, The COS files are written by COMIS at the end of a COMIS simulation. Therefore, they are not available when COMIS is used as a TRNSYS type. As far as...
Hello, I used to use COMIS several ago and have just coming back to it. Could any of the users of this group suggest any text that discusses how the nodes and...
See in: Fundamentals of the Multizone Air Flow Model- COMIS Edited by: Helmut E Feustel and Alison Raynor-Hoosen Francis Allard (France), Viktor B Dorer...
Thanks for the advice. I will attempt to get my library to get hold of it. While I am waiting, is there any source that is freely available on the internet. ...
