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 ...
Hi all, I'm using COMIS excel to do multiple runs and I want to choose the standard Monte Carlo or discrete parametric analysis (by leaving D13 empty) but the...

Regarding your pollutant stepping question, the answers below are correct for the old public-domain version of COMIS (3.0.2). They probably hold as well for...

Thanks so much for the help. I was able to implement POLSTEP using 3.2 with simulation studio. How do I specify that I want to save -S the concentration in...
Hello, When I input this, for instance: FL-S hf_4 hf_5 hf_6 hf_13 hf_14 hf_15 hf_22 hf_23 hf_24 hf_31 hf_32 hf_33 hf_40 hf_41 hf_42 I get an error b/c the...
Try: FL-S hf_4-hf_42 This will output the flow of all the links which are defined between hf_4 and hf_42 in the link list under &-NET-LINKs including the flow...
