SecParticle Solver Node set settings for the secondary liquid particles fluid simulation.
Input / Obstacle Grid:
Input obstacle object vdb data for simulation.
Output / Simulation Data:
output result simulation data.
Base Sim File:
set base simulation file for the secondary solver. The only files that can be used are simulated files created with the PIC/FLIP Solver and Terminal node. And only for files that exported without Channel Minimized.
