Particle Advection Node advect particles of simulation data.
If your system has nvidia’s 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 Particle 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, 0.2 – 0.8 makes good result.

Min Substep:
Defines minimum number of advection steps.
