Required parameters

CAVITY VOLUME

This parameter applies only to LKM analyses.

Set this parameter equal to the estimated maximum volume of the associated fluid cavity.

FLUID CAVITY REFNODE

This parameter applies only to LKM analyses.

Set this parameter equal to the name of the node set containing the associated fluid cavity reference node.

MAXIMUM NUMBER OF PARTICLES

Set this parameter equal to an upper bound of the maximum number of particles expected to be generated during the analysis.

NAME

Set this parameter equal to the name of the particle generator.

TYPE

Set this parameter equal to the type of particle to be generated. PD3D and PC3D elements are supported.

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.

RLDP

This parameter applies only to LKM analyses.

Set this parameter equal to the estimated ratio of the mean free path to the lumped molecule particle diameter. The default value is 500.

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 2.0Rmax in front of the inlet surface, where Rmax is the maximum particle radius for the generator. The default value is 0.4.
