Grid Advection Node advect channels of simulation grids.
If your system has nvidia cuda GPU and checked ‘Use Cuda GPU’ on the Simulation terminal node, use GPU computing for the advection.
If overflow memory for the GPU computing, automatically switch to the CPU computing mode.

Input / Simulation Data:
Input simulation data for Grid Advection. You must connect this input for work.

Output / Simulation Data:
output result simulation data.

Substep Sensitivity:
Defines substep sensitivity of the advection. Smaller values makes more sensitivity. High values makes advection errors around obstacles. Usually, 1.0 – 2.0 makes good result.

Min Substep:
Defines minimum number of advection steps.

Max Substep:
Defines maximum number of advection steps.

modify collision border:
When checked, avoid to make artifact on collision surface.

Field Advection Scheme:
Defines scheme of field (density, fuel, temperature and other) advection.

Velocity Advection Scheme:
Defines scheme of velocity field advection.

Vorticity Confinement:
When checked, activate vorticity confinement process through simulation.

Intensity:
Defines intensity of vorticity confinement. High values might cause dissipate and noisy result. Usually, 1.0 – 4.0 makes good result.

Adv. Vorticity Confinement:
When checked, activate advanced vorticity confinement process through simulation.

Adv. Intensity:
Defines intensity of advanced vorticity confinement. High values might cause dissipate. Usually, 0.1 – 0.5 makes good result.
