*TRACER PARTICLE
19.9 *TRACER PARTICLE: Define tracer particles for tracking the location of and results
at material points during a step.
This option is used to define tracer particles and assign them to tracer sets for tracking the location of and
results at material points during a step. The tracer set name is used in conjunction with the *ELEMENT
OUTPUT and/or the *NODE OUTPUT options to request output for the tracer particles associated with the
tracer set name.

Required parameter:
TRACER SET
Set this parameter equal to the name of the tracer set to which these tracer particles will be assigned.
Optional parameter:
PARTICLE BIRTH STAGES
Set this parameter equal to the number of tracer particle births within the step. If this parameter is
omitted, a single particle birth will occur at the beginning of the step. If this parameter has a value
n greater than one, tracer particles will leave their parent nodes n times during the step at equally
spaced intervals in time.
Data lines to define the tracer particles associated with the tracer set:
First line:
1. List of nodes or node set labels to be assigned as tracer particles corresponding to this tracer
set.
Repeat this data line as often as necessary. Up to 16 entries are allowed per line.
