Q.
I am trying to understand the meaning of the X, Y and Z forces in the time history plots for the gauges that I have applied to a model in AUTODYN 11.0
. What is the exact meaning of these forces and are they the reaction forces?

A.
The forces X, Y and Z listed in the time history plots are not reaction forces, they are the nodal forces required after update of the stress tensor as part of the Lagrangian computational cycle which result in nodal accelerations and velocities. They are not related to the reaction forces.

If you are interested in the reaction forces you need to instead look at the stresses in the model which you can then convert to forces. The stress that is recorded is STR.AVG.1 so you will need to select this from the time history plot to provide the correct information at the gauge locations. STR.AVG.1 gives the average stress at these locations.

You will need to select this result from the output tab ' history ' select gauge variables first and then re-run the model.
