eng.alasmari New Member Join Date: Mar 2016 Posts: 1 Rep Power: 0	Hello I was trying to simulate impact test for a very simple part. Anyway, I made the wall rigid and delete the connection between the part and the wall, but when I run the simulation the part goes through the wall (no impact occurs), if I bring the connection back, the part hits the wall and a deformation results appears. But in both cases the stress is still zero. I couldn't find out the problem, hope someone can help me. If you want to look to the file you can download it from here https://drive.google.com/open?id=0B_...msxbFpUdFNoU2c Regards
