Assessing Smoke Visibility Results

The Smoke visibility output quantity indicates how far away a sign is visible at every location in the model. The visibility distance near the burn source is typically very small because of heavy smoke. The visibility distance away from the burn source is usually significantly higher, indicating a reduced smoke concentration, and greater visibility.

Filtering, iso surfaces, and results plane are useful for effectively displaying smoke visibility. In the following images, the darker regions correspond to lower values of smoke visibility, and are close to the burn source:

To view the mass concentration of the fuel, display Scalar as the output quantity.
