mode=0 means

hi,

scene.fluidBlocks.append(Scenes.FluidBlock(id='Fluid', boxMin = [-1.5, 0.0, -1.5], boxMax = [-0.5, 2.0, -0.5], mode=0, initialVelocity=[0.0, 0.0, 0.0]))

in this code the initial condition of fluid is defined in fluidBlocks, what is the mode here means,

Best,

[BoyuanTang331]

is that represent for the sampling rate, how will this behaviour influence the simulation?

denseMode (int):
0: regular sampling
1: more dense sampling
2: dense sampling

Yes, it just defines how the fluid block is sampled. If you have a sparser sampling, then at the beginning of the simulation the block will be compressed a bit until you reach the rest density. So that is the only difference.
