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,
AlexÂ
