Produces sharper details, keeps vortices alive longer but uses more time and memory. Produces a somewhat blurrier result where vortices get smoothed away quicker, but it's also faster and uses less memory. The advection accuracy affects the sharpness of the details in the fluid. Unchecking this box is only useful for benchmarking and testing purposes. The Clip Below parameters in the Velocity, Temperature, Density, Fuel and Burn tabs control when TFD may shrink the container.

If enabled, TFD simulates the smallest possible part of the container in order to save time and memory. For simulations that don't have collisions and mostly moderate velocities, the simulation time can be kept lower by using the minimum of one iteration. Values larger than 10 should rarely be necessary. It is a fundamental part of the simulation to equalize this pressure.įor simulations that have high velocities and/or collision objects or closed container boundaries, it is recommended to use values between 2 and 10. Wherever velocity deforms the fluid, pressure is build up. The simulation will also take more time, though. This will allow the simulation to resolve the fluid motion better. If your simulation has high velocities and you're seeing noise artefacts in the flow, allow the simulation to take more sub-frame time slices if necessary by increasing this value.
