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.
Let’s go through the settings for the flow object and learn about each one:
- There are four Flow Types we can add:
- Smoke will only emit smoke into the domain.
- Smoke + Fire will emit both smoke and fire into the domain.
- Fire 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, of course, will emit fluid into the domain.
- Flow Behavior controls how the flow will interact with the simulation:
- Inflow will constantly add fluid/smoke to the simulation.
- Outflow will remove any fluid/smoke it touches from the simulation. This can be useful for creating a drain or vacuum or to prevent the entire...
