Painting Temperature values into a container

By default, the Fuel and Density will react when there is no Temperature in the container, but adding higher temperature values will make the reaction more immediate.

To paint Temperature values into a container

In the Tool Settings window, beside Paintable Attributes, select Temperature. A message appears prompting you to set the fluid’s Temperature method to Dynamic Grid or Static Grid.
By setting the Temperature method to Dynamic Grid, the temperature values you place in the container grid are recalculated by the fluid dynamics solver and changed during simulation.

By setting the Temperature method to Static Grid, the temperature values you place in the container grid are used by the fluid dynamics solver during the simulation, but they cannot change during the simulation. Static Grid is useful when you want to define specific values in specific areas of the container, but you do not want these values to change over time.
Click Set to Dynamic. The Density and Fuel values disappear. The values are still there, but only Temperature values now display. Currently there are no temperature values in the container.
Change the brush so you can paint through the entire thickness of the slice with a single stroke. In the Stroke section of the Tool Settings window, change Stamp Depth (3D) to 2. The brush changes, showing how deep the brush stroke will paint.

If you make the brush depth thicker than the depth of the slice, only the space within the slice will be painted.
Paint a small amount of Temperature in the center of the slice.

The stroke adds Temperature values through the entire thickness of the slice.

The next steps are to view all the property values together, and color the properties to differentiate them.
