Flow objects
Flow objects are used to either add smoke/fluid to the simulation or remove it, and they must be within the domain bounding box to work properly. To add a flow object to the simulation, just select any mesh. Then, in the Physics panel, select Fluid | Type | Flow.
Figure 2.51 – Flow settings
Let’s go through the settings for the flow object and learn about each one:
- There are four flow types we can add:
- Smoke: This will only emit smoke into the domain.
- Smoke + Fire: This will emit both smoke and fire into the domain.
- Fire: This will only emit fire. Keep in mind that a little bit of smoke will be emitted from the burnt fuel. If you only want fire, set Flame Smoke in the domain to
0. - Liquid: This, of course, will emit fluid into the domain.
- Flow Behavior: This controls how the flow will interact with the simulation:
- Inflow: This will constantly add fluid/smoke to the simulation.
- Outflow: This will remove any fluid/smoke that...
