I used Houdini to simulate a pile of burning tires to show both fire and smoke. I used two pyro presets to create my effect. Even though Houdini provides a number of presets for visual effects, these are just a jumping off point. It still requires adjusting attributes such as temperature diffusion, cooling rate and burn rate to get the right look for an effect.
In this project, I brought in a pile of tires for the initial geometry. I imported a second set of tires to be attached to the smokeless flames. This made it look more like the top of the tires were burning. I then imported another set of tires for the smoke. I used the volcano pyro to create this effect. To finish off the look, I imported multiple copies of the tires in order to have a field of tires.
