High Energy Error

Hello,

 

for my Formula Student Team I am trying to simulate the deformation of the Anti Intrusion Plate. To replicate the real test I've tried to implement the Honeycomb Impact Attenuator Tutorial(https://altairuniversity.com/wp-content/uploads/2016/11/Crash_Box_1.pdf). I've attached the file. When I try to run the simulation the Energy Errror starts at 0% and then rockets up to 99.9%. Then the Simulation stops.
