Hi, currently I am doing a Car Crash on barrier at V=80km/h but for some reason it always shows this error: forrtl: severe (157): Program Exception - access violation. Attached on this post are my files. Would love to see what I have done wrong. Thank you so much.

1) Check for duplicates
2) Check for free rigids or other elements
3) Check all contacts again
4)check material properties
5) sometimes part get crushed and inserted in itself which may also cause this problems.
6) change solver type.
also not able to download your files from the post.
