Hi, 1. I want to create random circle geometry ( nanoparticles) on 2D comsol. But with array function, they're not random. How can I do it?

  1. How to simulate the concentration of nanoparticles in fluid with 2D?

Thank you so much!

Hello,

1/ You need to work in 3D, not 2D, otherwise your particles are cylindrical not spherical.

2/ see this blog to learn how to create randomized geometries through scripting.

Best,

Jeff
