Simulation Settings

Change the Simulation Scale value to emulate various simulation sizes whilst keeping the bounds and voxels sizes the same.

Tweak the Sim Speed parameter to achieve slow-motion and speed ramping effects.

Create a shockwave explosion by animating the Sim Speed value.

Learn how each fluid channel has its own buoyancy parameter and how changing them from positive to negative can invert our volume's vertical motion.

Increase Vorticity to add smaller details to ExplosiaFX simulations and encourage curling motion.

Use Turbulence to add random natural motion to the volume.

Explore the Chemical burning model to emulate real-world combustion.

Change to the Custom Burn Model to use sliders and curves for finer control.

Use separate ExplosiaFX Sources with Fuel and Heat to create an ignition effect.

Tweak the diffusion and dissipation settings to soften and remove fuel and smoke over time.

A technical deep dive on the Substeps settings in the ExplosiaFX solver.

Learn about scenarios that require more substeps or accuracy to keep them stable.

Compare various substeps settings and learn how the CFL slider helps to set them.
