MPM Solver Node set parameters for the MPM(Material Point Method) fluid simulation. If your system has nvidia cuda GPU and checked ‘Use Cuda GPU’ on the Simulation terminal node, use GPU computing. If overflow memory for the GPU computing, automatically switch to the CPU computing mode.

Input / Emitter Particles:
Input emitter for simulation. You must connect this input for work.

Input / Obstacle Grid:
Input obstacle object vdb data for simulation.

Output / Simulation Data:
output result simulation data.

Time Speed FPS [frame / sec]:
Defines frame rate for the simulation.

Global Sticky:
When checked, add global sticky status.

Global Friction:
Defines global friction intensity of collision surface.

Solver Scheme:
Defines MPM solver scheme.
Flip: Flip scheme is fast and less memory usage. This scheme is match for snow material.
APIC: APIC scheme is more accurate for energy transfer.
MLS: MSL scheme is similer result with APIC but more optimized.

PIC/Flip:
Defines weight of the velocity transfer method. 1.0 means totally Flip simulation. 0.0 means totally PIC simulation.
