Floating particle simulation in PhoenixFD liquid using buoyancy operator
show user profile  TurboRudi
Ok so I have a project where there's dirty water coming out of a pipe and going through a filter system in a tank and gets purified.

I'm using Phoenix FD to simulate the liquid. The liquid is filling the tank appropriately but now i need to add particles(dirt) that comes out of the pipe, enters the tank and drifts around in the water.

The best I've come up with is using Pflow, adding a phoenix force- (so that the liquid force drives the motion of the particles) and buoyancy operators.

Problem is I cannot find a way to animate the plane that the buoyancy uses as a water level so that different polygons of the plane rise at different times (the tank has compartments that fill up seperately)

Is it possible to animate sub-objects?

Is there an easier way to do this? Maybe some buoyancy script that works better than the built in operator? I preffer simulation over faking it with forces.

I will also need to add oil that floats on top of the water, is there a way to let a liquid float in another liquid with phoenixFD? I have googled the topic for weeks and can't find ANY material related to simulating floating objects except in game engines.
