HySPH Bubbles Simulation

HySPH Bubbles Simulation

17 Aug, 2015

Starting point for splashes is always an existing HyFLIP simulation. Here it is the simulation from → "Quick Start Tutorials - HyFLIP Fluid Simulation".

 

 

Quick Start

  • Set the domain's simulation state to → “Cache” (“yellow rocket”).

  • Other, already simulated HySPH emitters have be set to “Cache” as well.

  • Add a “Bubbles” emitter from the “Hybrido” shelf.

  • Reset the scene.

 

 

What you see now is a cross in the viewport's centre, indicating that the emitter is not bounded. You can prevent the particles from leaving the domain:

  • If not done already add a → “k Volume” daemon and adjust it to the scene with the R key.

  • Or make sure that the bubbles particles will be enclosed inside a container or a cube.

 

You can control the emission of particles with the parameters under → “Bubbles Creation”:

 

 

  • Two threshold values are used to control in which parts of the HyFLIP fluid splashes will occur.

  • The higher the thresholds, the less particles you will get.

  • The “Emission rate” parameter is also responsible for the number of particles.

 

If you want to control the bubble's rising speed go to → “Bubbles Dynamics”. The most relevant parameter is “Buoyancy force”.
