* COMPUTE THE IIHS DISPLACEMENT INTRUSIONS OF THE POINT BASED ON THE AVERAGE SEAT MOTION*
=========================================================================================

Computes the IIHS displacement intrusion of a structural node relative to the average seat motion by differencing the node's X/Y/Z displacement curves from the corresponding seat reference curves. Use this worker to derive intrusion time-histories for IIHS small-overlap or side-impact evaluations where seat-relative displacement is the relevant metric.

     - Time-history curve of the average seat Y-axis displacement (mm vs. time); used as the seat reference baseline in the lateral direction. Optional — omit if the Y component is not needed for the intrusion calculation.
