Hi,

I am trying to model an impact attenuator. I give a prescribed velocity of 7 m/s to a rectangle made of steel, but even if i crate contact between this rectangle and the impact attenuator (polygon made of foam) this doesn't move towards another rectangle of steel to simulate the crash. If i follow the model of "Hyperelastic seal" and give a prescribed displacement, it moves, but i want to know the deceleration of the 1st rectangle.

I hope you can help me,

Thanks,

Javier
