I have set up a spring/damper combination between two
vertical, colinear faces in a Motion Analysis. I am trying to find
the distance between the two faces and the relative velocity
between the two faces when the whole system is oscillating... Is
there a way to do this?

Any help is appreciated!

The way you would do this depends on the version you have. Is this 2008 or later?

You can define function expressions to measure just the horizontal distance/velocity and use that to compute the force response.
