Thank you so much sir for your valuable response. 

I'm going to give it a try.

Hello Everyone,

I hope you guys would be fine. I want to do gas simulation in ventsim 5.4. I have a few queries if you can help me with that.

1) How can I add do gas/contaminant simulation of more than one gases? That is, I want to see its spread with the addition of a fan? The concentration of contaminants are fixed. I just want to exhaust them.

2) How can I add a radioactive gas into it other than radon? Or can I change the properties of radon to fake it to any other gas

3)if I have more than one contaminants, having fixed concentration. Then how can I simulate them? Can i input them in one simulation model at a time? 

4) is it possible to use radon as well as contamination simulation option at once? If yes then how can I interpret the result then.

Hello! I want to simulate the dilution of tritium (a radioactive gas) in an airway, however in ventsim design 4, only radon is there. Is there anyway I can add tritium there??

Hello everyone!

I want to model the ventilation system of a tunnel. I'm using SS Jet fan by EMAK. In product catalog of EMAK, there isn't any fan curve given for the said fan. 

Someone please help me how can I estimate the fan curve of the said Fan?

Thanks
