Hi
I want to simulated the external cfd for an office room with some people that one of them Coughing, and the air flow come from the window , from a cuboidal enclosure . when I set all of that, gives me an error, about that you have more than one solid . After that I boolean union all of the boxes and import one solid (from Rhino) and the error has been solved but now I can not choose the surface for Coughing or in set boundary condition , my layers does not come and I can not define tables or people or any thing else.
please help me
what is wrong ? what I should be do?
How can I choose the surface for Coughing , after Create flow region?
and I have another question , in one of the page I saw the simulated CO2 concentration (Using CFD to Simulate Ventilation Equipment | Blog | SimScale) but Ido not Understand , how do it
please help me
