Tracers are available in the LS-DYNA system for ALE and S-ALE simulations and have been added to Mechanical as ACTDYNA objects. The Tracer adds a tracer particle, which saves the history of either a material point or a spatial point to an ASCII file called trhist and a binary file called binout. These files can be found inside the solver folder.
At run time 2 keywords are written:
*DATABASE_TRHIST – Specifies the output type, which are ASCII and binary.
*DATABASE_TRACER – Provides details of the tracer.
