PIC/FLIP Terminal Node defines general parameter of PIC/Flip liquid simulation.
This node must be used with PIC/FLIP Soler node.

Input / Simulation Data:
Input simulation data for PIC/FLIP Terminal. You must connect this input for work.

Export Files:
Defines export placement of the simulated PRT data.

export Vorticity Channel:
When checked, export vorticity channel.

export Curvature Channel:
When checked, export curvature channel.

save float as 16bit:
When checked, export float channel as 16bit for the prt file to reduce file size at the expense of some accuracy.

Channel minimize:
When checked, minimize export channel. By limiting the kinds of channels output, reduce the size of the output file, but you will not be able to use Resume Simulation and SecParticle Solver.

Export Log:
When checked, export simulation log.

Start Frame:
Defines start frame of the simulation.

End Frame:
Defines end frame of the simulation.

Timestep Sensitivity:
Defines CFL condition of the simulation. Smaller values makes more sensitivity. Higher values get unstable of the grid simulation. Usually, 2.0 – 5.0 makes good result.

Min Timestep:
Defines minimum number of Timestep Sensitivity.

Max Timestep:
Defines maximum number of Timestep Sensitivity.

Viewport Preview:
When checked, preview particles during simulation.

Max Velocity:
Defines maximum velocity of particle preview color. If particle velocity is larger than this value, particle color get white.

reduce step:
Defines step size for particle preview. To set 1 means all particle previewed. To set 2 means half particle previewed.

Resume Simulation:
When checked, use resume simulation mode.

Resume Frame:
Defines resume frame. When use resume mode, start simulation from this value of the frame. You need correct simulation data (Don’t use check “Channel minimize”) of this frame in the export folder. You can use “save float as 16bit” with resume, but resume result may slightly changed from original simulation result.

Use Cuda GPU:
When checked, use cuda GPU computing over the simulation.

Sim on network rendering:
When checked, start simulation when 3dsmax on the network rendering(slave) mode. Be careful, when use this mode, please set “single frame rendering” in your render setting. If you set multiple frame rendering with this check, execute simulation on the every render tasks.

Start Simulation:
When you crick this button, simulation process start on your PC.
