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...
Hello group Under &-WI, what is the value for Cs for open doors? Cs is defined as flow coefficient for close windows per m crack length. If the door or window...
... The Cs value (in the second row of the *W block) describes the window/door leakage when it is closed. As the window/door opens, the airflow is determined...

As far as I know, this version does not run on Windows XP. I guess that might be the problem. Nicolas Heijmans Belgian Building Research Institute (CSTC - WTCB...
COMIS 3.1 does run on Windows XP, as well as its graphical interface. But you should not use the old (outdated link) to access it. The right link is ...
dear Werner and Nicolas Heijmans Thank you very much for your responds. I have download the COMIS 3.2 from http://software.cstb.fr/soft/present.asp?langue=us....
The older versions of COMIS also run on XP, as far as the kernel is concerned. The graphical User Interface, however, does not run on XP. You could try to use...
Hi there: I found this mistake message: the pollutant name co2 in schedule Qco2 matches none of the pollutants. Correct the input at &-NET-ZONE or &-POL-DES...
Dear all: I read about the content on histograms in the Comis user guide, but I wonder how I can difine the histograms in simulation studio? Thanks a lot!...
