Hi,

I am trying to model the transient response of a free-free beam (unconstrained) in ABAQUS, where the force is applied through a spring. I am using a two point spring where one end is connected to the beam and the other a reference point, the force is applied to this reference point.

When i visualise the results the spring is showing no results (white) even though I requested the the node set of the reference point.

The beam response is the same as it was without the spring no matter the choice of spring stiffness selected. So i assume the spring is incorrectly modelled.

Have i made a mistake when modelling the spring?
