This page provides a tutorial for manually creating a heavy smoke effect for a fire simulation.

## **Steps**

---

1. Start with a fire simulation such as the [Simple Fire Simulation](https://docs-chaos.atlassian.net/wiki/spaces/PHX4MAYA/pages/125898877).
2. Select the [Phoenix Source](https://docs-chaos.atlassian.net/wiki/spaces/PHX4MAYA/pages/125895595) and decrease the **Temperature** below 300 Kelvin. This will make the emitted fluid heavier than the empty cells and cause it to sink. <span style="color: #1c1e21">You can find out more about Phoenix Grid Channel Ranges </span>[here](https://docs-chaos.atlassian.net/wiki/spaces/PHX4MAYA/pages/125895763)<span style="color: #1c1e21">.</span>
3. <span style="color: #1c1e21"> </span>Increase the amount of **Smoke **that will be emitted.
4. Select the Phoenix Simulator. In the [Dynamics rollout](https://docs-chaos.atlassian.net/wiki/spaces/PHX4MAYA/pages/125735689), make sure that **Uniform Density** parameter is disabled.
5. In the [Output rollout](https://docs-chaos.atlassian.net/wiki/spaces/PHX4MAYA/pages/126029700), make sure the **Smoke** parameter is enabled.
6. If the emissive component is not needed for rendering, uncheck the **Temperature** in the same section.
7. Start the simulation.
