How to:

You can select the scene from 'Assets/Scenes'. Once in the scene, you can hit play to see the simulation. You can change some settings in the script from the MANAGER GameObject.

Settings:

Single-thread:

  • Particle count
  • Particle parameters*

ECS, Job system:

  • Particle count You can find the particle parameters* inside 'Assets/Job System/Prefabs' in the SPHSphereECS GameObject.
  • Particle parameters:
    • radius
    • smoothing radius
    • rest density
    • gravity multiplier
    • mass
    • viscosity
    • drag
