Reply To: Collision study in Ansys LS Dyna

Hi Mans,

Your setup looks good to me. If you have already defined all contact pairs manually, I would suggest deactivating “Body Interactions” since they sometimes interfere with manual contacts.
To check what happens after the impact, you can check the velocity of the drone after collision.

You have employed a proper tool (explicit solver of Ansys LS-DYNA) to evaluate this type of simulation. In general, explicit dynamics analysis is appropriate for short duration events that may include significant nonlinearities.
