ACP with explicit dynamics, part penetrates into the solid wall

      1. I have created a solid model of car bumper in ACP and transferred the setup to Explicit dynamics to perform crash. When I try to simulate, the body goes into the wall and does not deform properly. what am I doing wrong here.

      What do you have under connections? Use Body Interactions if you aren't doing this already. Also, set the scale to true Scale.


      If these don't help, please post snapshots of you contact settings.

      thank you sandeep.


      there are body interactions by default. i am getting this problem when there are "upside down elements" in the solid model.


      although i export shell composite data into explicit dynamics, i was checking for upside down elements in solid model and when there are no such upside down elements, the material deforms properly.


      can you please tell me how i can prevent upsidedown elements
