Hello everybody


I'm a beginner at Ansys fluent and still know very little. For a project at the university, we should 
simulate and appropriately presentingthe smoke-free layer in a room (2-D). The simulation of fire is 
uninteresting.



Does anyone have an instruction or similar? Unfortunately, I did not find anything suitable on youtube.



I would be very happy about tips and tricks.



Many thanks and greetings from Germany.

Very simple approach is to model smoke as additional passive scalar (UDS) with a source of mass concentration into the domain or as discrete passive particle. You make it a bit more high end by using a source term to account for heat source due to smoke addition.
