My case is simulating a smoke inside a room.
I have created the whole room domain as as one zone and I created a boundary edge to set it as the smoke inlet while the room is initially containing air only.

How can I simulate this case?
I tried the species transport model and set the smoke entry as mass flow rate, but I don't know how to set the main domain initially as air.
Is this the correct model?
should I split the smoke source into another domain ?

Thanks in advance

Hi,

Species transport model might be correct (even though smoke is composed of solid particles as well) but you need to define your smoke properties

To initialize the domain with only air, there’s a button somewhere in solution initialization to use standard initialization, so that then you can select the exact values with which your solution is started

Thanks for your reply
Do you mean I should define the smoke properties from fluent or as external UDF file?
about the initialization I didn't understand how to initialize the domain as air.
Can u specify more detailed steps please

Make the initialization and than go to the initialization panel and choose patch, there it should be possible to define composition.

Thank you very much, this was very useful
