Change number and size of particles in a particle system

[arjunsohal12]

I have created a particle system using a particle sampler to create a liquid simulation. However, when the cube is very small Isaac Sim creates perhaps 10 particles in the system, in order to accurately simulate the liquid I need more than this. Is there a way to modify the number of particles in a system, and perhaps the size?

Hi @arjunsohal12 ,

I assume you use the particle sampler to convert a mesh to particles? If yes, please read both about the particle system configuration:
https://docs.omniverse.nvidia.com/extensions/latest/ext_physics/physics-particles.html#particle-system-configuration

And about the sampler:

Using appropriate offsets and sampler parameters will let you achieve a higher particle resolution.
