Good morning everyone, I'm trying to implement a simple sum of step functions that changes the force value depending on the distance between two markers. In my case it is a sum of three STEP5 of this type: STEP5(DM(A,B),D1,F1,D2,0)+STEP5(DM(A,B),D3,F2,D4,0)+STEP5(DM(A,B),D5,F3,D6,0). What happens is that the force is actually applied following the sum of steps that I would like, but once we reach the end of the application of the force this is mirrored symmetrically. To be clear, I would like to simulate the resistance applied by two series honeycomb dampers. How can I avoid this repetition of the application of the force in the opposite direction? And above all, why does it do it? Thank you
