The positions and velocities of locations on the zone can be sampled and stored during a model run by using this command. The resulting path through space can be visualized with the FLAC3D interface. Only one trace position may be created per zone trace command. Traces may be added at any time.

A summary of all traces can be obtained by using the trace list command.
