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
