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...
Hello! I am a novice at using COMIS, and I'm trying to figure out how to use the Simulation Studio interface. I'm trying to put a CO source into one of my...
Hi Nasim, To add a CO source to a zone, simply 1- double-click on the zone and go to the 'Pollutants' tab 2- click on Pollutant 3 (CO); note that this...

Hello! all users of Comis.. We are about to purchase Comis 3.2 But I wonder that it is possible Microsoft Windows XP version.! In XP enivironment, If Comis 3.2...
Hi Kim, We run comis 3.1 under XP, so I guess 3.2 should not be a problem, though we do not have 3.2 Good luck Stefan ... Van: comis@yahoogroups.com...
Comis 3.2 runs perfect under Windows XP. The simulation engine of Comis 3.1 together with the EXCEL user interface runs as well under XP, but not IISiBat...
Dear all, I just started to use Comis. I downloaded the demo version of Comis 3.2 with all the manuals attached. I want to use comis to analyse a car park...
i have the problem with the download of the comis with the web..is there other site when i can find the programme? Not that I know of. But you can get help...
... It looks like COMIS is trying to read your schedule information as a "3D" pressure-- which appears in the column before the schedule column. Try inserting...

Yep, that seemed to work fine, thanks very much. ... a ... column. ... runs, ... and...
When I print my output of the pressure flow of internal zone (PZ-S) to/and external zone (PE-S) then is the flow direction to the outside, but the pressure...
Zone pressures are related to the zone reference height and outside pressure to building reference height. If the link is not located at these reference...
Thank you for the fast answer. In my model the zone reference heights are different from the building reference height. So I think you are right, but how can I...
Hi comisuser, There is a great chapter in the COMIS User Guide about this problem, with a picture of a multi-story building. You find it in the Simulation...
You don't have to change this, if it reflects the situation of your building. The meaning of my answer was: there is nothing wrong about results like this, as...
I have read that part of the documentation and I think understand what happens. But I don't know how I can model the reference heights on the same level as the...
Hello, I am currently doing a simulation coupling trnsys and comis and i get two times the following error on comis: the maximum number of iteration steps has...
... Here are some simple things to try, all in the &-PR-CONT section of the input file: (1) Increase the "max number of iterations allowed" e.g. from 500 to ...

Thank you for your prompt reply! I have run my simulation after increasing the number of iterations ( from 1000 to 1000000) and I have mot anymore my previous...
Elisabeth, Could you send us the complete error message (or the entire list file), please ? This sounds like a TRNSYS error, but I'm not quite sure... Werner ...
Dear COMIS user, TRNSYS 16.1 allows to create 2 new project types : « COMIS Project » and « Coupled Project ». A limited version of the COMIS simulator is ...
