Body Penetration

    • luis.serra5

      How can I avoid and fix the interpenetration between bodies in an impact simulation? The next printscreen shows my issue. My body interactions are all defined as "Frictionless" and I didn't use any type of contacts, bodies are connected with springs and fixed joints.

      Hi Luis,


      Are you expecting the parts to interpenetrate? Can you try defining the contact region?

      Hi Ashish!

      No, that's not what I want. I want to see part's behavior after a car impact and interpenetration is not expected. I tried to define some contact pairs but this problem is still happening. I am using shell elements in the mesh.

      Thank you for your answer. Regards,
