  Hello everyone,nI am trying to simulate the motion of solid particles in a cylinder filled with air in ANSYS FLUENT. but it was difficult to insert the particles in different size (1 mm &10 cm) into the domain. I want them to be already present in the domain at t=0 with random initial distribution. I want to perform particle tracking in the Lagrangian frame after different intervals of time. nI have inserted the particle using injection file, but for uniform particle diameter and distribution. It is possible to add 200 particles in different diameter size with a random initial distribution and radial initial velocity in the domain without having to inject them.nThanks in advance!n

  You can use an injection file, you just need to randomise whichever numbers you want. Without an injection there can be no particles. n

  Thank you Rob! I solved it. I create additional injection file and I set a random position of the particle,
