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.
Set this parameter equal to the name of the tracer set to which these tracer
particles will be assigned.
Optional parameters
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
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.
