Creates a container that can hold a flamefront.

Once the fuel burns it will produce smoke and soot. It can be used, for example, to hold and simulate a candle.

Using Flamefront Container

  1. Click the Flamefront Container tool on the Volume Fluids tab.

  2. Place the container anywhere in the scene view.

To...Do this

Create fire in the container

  1. Place a geometry object inside the container.

  2. Use the Source from volume tool to turn the geometry object into a fire object.

  3. On the object DOP, increase the Temperature on the Physical tab.

    By default the temperature is set to 0. The fuel will not ignite if the temperature is not hot enough.

    You can also increase the temperature of a nearby fire object, which will ignite the source object.

Change the amount of divisions in the container

Edit the Divisions on the operation controls toolbar or in the parameter editor.

Reducing the divisions will make your simulation faster and increasing the divisions will make your simulations more detailed.

Let the smoke escape the boundaries of the container

Turn off the Closed Boundaries checkbox on the operation controls toolbar or in the parameter editor.


The large tick marks indicate 10 divisions. So, the flamefront container in this example has 20 divisions.

A possible next step could be to eliminate some smoke and soot. To remove smoke and soot from a simulation, use the Sink from Objects tool on the Fluids shelf.

You may also want to add some turbulence to your smoke and soot. You can do this by applying Seed Vorticles.
