*PARTICLE GENERATOR

Optional parameters

MAX ATTEMPTS PER INCREMENT

Set this parameter equal to the maximum number of particle insertion attempt cycles the generator makes before halting generation for an increment. The default value is 10.

MAX INSERTION ATTEMPTS

Set this parameter equal to the maximum number of attempts the generator makes to place a particle of a given size before rejecting that particle size. The default value is 15.

SOLID FRACTION

Set this parameter equal to a threshold value that will temporarily halt the particle generator for an increment if the region near the inlet has a high volume of particles. The threshold value is a particle volume fraction over a volume that extends $2.0R_{max}$ in front of the inlet surface, where $R_{max}$ is the maximum particle radius for the generator. The default value is 0.4.
