This simulation process produces a voxel grid for each frame, which is cached on disk for use by the Volumetric Renderer.

For each voxel TurbulenceFD calculates the velocity of the fluid as well as several channels to describe properties like temperature, smoke density, amount of fuel, etc. That means it uses a voxel grid to describe the volumetric clouds of smoke and fire and solves the equations that describe the motion of fluid on that grid. This value specifies how fast the turbulence field changes over time.TurbulenceFD’s simulation pipeline implements a voxel-based solver based on the incompressible Navier Stokes equations.

A small power of 0.5 will make small curls half as strong as curls of twice the size.

A small power of 1.0 will make curls of all sizes equally strong. Specifies how strong small curls are with respect to the next larger ones. Specifies the size of the largest curls added to the fluid. Specifies the size of the smallest curls added to the fluid. Use this to add turbulence only where the temperature is high enough, for example.įor improved control over the intensities, the values of the Intensity Channel are re-mapped by this f-curve before scaling the turbulence intensity. You can control the turbulence intensity in space using any of the fluid channels. Specifies the strength of the turbulence.

The following parameters control the intensity, scale, etc. It is driven by a procedural noise function that changes over time. Adds random velocity noise to the container, making it swirl and a chaotic way as you would expect from turbulent fire or similar.
