hi~
I try to do the smoke visbility on Autodesk CFD simulatio, but i can't generate the smoke in CFD
i follow the GuideLine, but it is still not success.
Can anyone help me here ???

I created a house with two holes. One is on the side, One is on the ceiling.
In the middle of the house there is a box where the fire generated.

material
Volume inside the the house is air. I set it to be variable.
The wall of the house is brick. The box in the middle is made by hardwood.

Boundary Condition
Box: Scale = 1, Heat Generation = 2000W
Air: Film Coefficient = 5 W/m2/K, Ref. Temp. = 19 Degree
Hole on Ceiling: Volumetic Flow Rate = 50 L/s,
Hole on Side : Pressure = 0Pa , Temperature = 20 Degree.

Solve:
Set Smoke Visibility on
Heat Transfer on
Specific Extinction Coefficient = 21000
The sign visibility constant characterizes = 3
combustion particulate yield = 0.08
Diffusion Cosfficient = 16 mm^2/s

Solution :
i set the output quantity is Scalar

However, i cannot see the smoke in the CFD.
Can Anyone help me
I want to create the view like the one in the Guideline. Smoke visibility
