nxFluids
nxFluids enables you to setup fluid simulations with a choice of solvers: PBD (position-based dynamics), SPH (Smoothed-Particle Hydrodynamics) and the grid-based FLIP/APIC solvers.
PBD and SPH are both fast, accurate and provide realistic fluid motion, which can make it difficult to decide which to use.
Generally speaking, SPH should be the choice for mid to large scale scenes where realism is key. SPH is also able to solve granular simulations for snow and sand scenes.
PBD is better suited to small to mid-scale scenes. It also works very well alongside nxConstraints and modifiers to create stylised simulations that push the boundaries of what is physically accurate.
FLIP and APIC are grid-based solvers suited to large-scale, high-detail simulations. FLIP blends grid-based and particle-based velocity updates, while APIC preserves more angular momentum for a more energetic, swirling result.

Groups Affected tab
Section titled “Groups Affected tab”Groups
Section titled “Groups”To specify the group, drag and drop the desired Group object into this field.
This setting is useful if you want to ensure that the spawned particles are, or are not, affected by nxFluids.
Mapping tab
Section titled “Mapping tab”The modifier’s settings can be mapped to particle data.
Use the dedicated manual page, below, for instructions on how this works.
Fields tab
Section titled “Fields tab”You can use the Fields options to control where nxFluids operates.
nxFluids tags enable you to individually set the fluid properties per emitter, to give individual emitters their own liquid settings.
This enables the mixing of different fluid types like oil and water.
