The biggest technological challenge in fluid simulation is the handling of the large amounts of data that a sequence of voxel grids requires. The flow then carries along these emissions in a physically plausbile way that creates the realistic look of fire, explosions, vapor, clouds, dust and much more. To setup a fluid simulation, the artist uses any type of geometric object or particle system to paint the sources of smoke, heat, fuel, etc. 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. TurbulenceFD’s simulation pipeline implements a voxel-based solver based on the incompressible Navier Stokes equations.
TurbulenceFD integrates seamlessly with your pipeline supporting Cinema 4D, Lightwave, Realflow, X-Particles as well as Redshift, Arnold, Octane and Cycles 4D render engines. Run fast GPU-based simulations and fall back to CPU mode if you need more memory for large-scale simulations. Create complex physical animations of gaseous fluid phenomenaĪdd fire, smoke, vapor, dust, clouds and similar effects into your existing scenes with an intuitive workflow. TurbulenceFD is easy-to-use, with an intuitive workflow, and is extremely fast, designed to exploit high-end GPUs and CPUS with even vast simulation data. Get unparalleled realism and control with voxel-based gaseous fluid dynamics, a physically-based fire shader, Particle Advection, and Multiple Scattering. TurbulenceFD has all the features that a visual effects artist needs to create organic looking particles. Generate realistic fluids, vapor, dust and other particle-based phenomena directly in Lightwave 3D.
