Hello, Mitsutoshi, You can try our model COwZ (COMIS with sub-zones). There are no limits for the zone number. You can also get details of airflows,...
Dear COMIS users It is written on the user's guide that some couple of data(pressure and airflow rate) can be used as the performance of a fan. And it seems...
Hello, I don 't know TRNFLOW, but if its like in COMIS, fans are defined by a fan curve. There are two ways of doing this, either by giving data pairs or ...
... Typically in COMIS the pressure that drives flow through a link is the hydrostatic pressure difference. The exception is when the link connects to an...

Hello, Does Comis adjust the Cp-values at an open window automatic? Or does it still use the values that are given as input? Thanks....
Dear all The different positions of a facade have the different Cp values, but in the &-CP-VALUes, it is only need to input one Cp value for a whole facade...
Dear Wangke, ... I usually get CPCALC (or the program that I prefer: CpGenerator) to calculate Cp values for various places on the facade to see the extent of ...
... The answer here is based on COMIS 3.0, the last public-domain version of the program. I imagine the current version of the code has the same basic design,...

Hello, I see that COMIS has the capability to specify ducts that connect zones. However, are these ducts associated with an air handling unit that can...
Dear Lisa Yes, COMIS can model ductwork. There are a number of built-in ductwork components, such as bends and T-sections, for which COMIS calculates pressure...
Dear all: I have a problem on coupling TRNSYS16 & COMIS 3.2 with Type 157. Three notices and three error messages were found acoording to project log, as...
Read the readme.txt file in .\comis32\Binary\Trnsys16 of your COMIS 3.2 installation to see which dll you have to copy into your TRNSYS directories. ...
I will be out of the office until March 9th. Please excuse the delay in responding to your email. ... To: <comis@yahoogroups.com> From: "Andreas Weber"...
Dear Andreas Thank you for quick reply. After copying Type157.dll, I had another error message: Visual Fortran run-time error forrtl: severe (29) file not...
Dear khrgen, This error means that the external file number 31 cannot be opened when you start the simulation. If you have generated the project with 'coupled...
Dear Andreas and Werner Thank you for your advice. I edited COMIS Studio.ini file according to the COMIS tutorial. However, some errors were still found. Do I...

Errors when coupling TRNSYS16 & COMIS 3.2 was successfully dissolved, after TRNSYS version was upgraded from 16.0 to 16.1. However, new errors occurred in...
hello everybody, i am modifiying a comis file which has already been done by someonelse to use it in a COMIS/TRNSYS simulation. in this file there is a...
This problem is usually linked to a problem in the COMIS network definition, such as an isolated zone, no external node, etc. Please check your network...
Dear Elisabeth, The external node component is necessary to connect an air flow component to a façade element. It should contain one parameter, which is the...
I have to model in comis several circular ridge vents with a horizontal axis pivoting. i can't figure out the difference between the component window (used...
Hi: I am currently doing a model of an office building. I used to model that in CONTAM and TRNSYS separately, and use TRNSYS Simulation Studio to couple them....
Hi, If you have TRNSYS 16.1, it contains a demo version of COMIS (max. 10 zones, 20 links). If you have a previous version of TRNSYS 16.x, you should get a...
