  I tried to simulate a collision in LS-DYNA. but what i found is my model penetrate to other body which supposed to be solid. the other problem is i can't find the impact on the striking area. any idea what should i do to fix this problem?

  Hi Ariq,
  Could you describe the way you considered the interactions between the two parts in your model? Did you specify any contacts or body interactions?

  Hello Ariq,
  Please find attached an article about the contacts in LS-DYNA for a full vehicle impact scenario. https://www.dynasupport.com/tutorial/contact-modeling-in-ls-dyna/modeling-guidelines-for-full-vehicle-contact
  If you are missing a contact card, please add it to the input deck. I would suggest starting with *CONTACT_AUTOMATIC_SINGLE_SURFACE.
  Please let us know how it goes.
  Thank you,
  Alex
