Reply To: No gravity effect with *LOAD_BODY_Z in LS Dyna

I don’t know for sure but I suspect you need to apply the gravity load during dynamic relaxation and not just in normal phase alone.   given SIDR=0 in your define_curve, maybe try to include DR and see if your model behaves correctly.

I have to say, I can’t 100% exactly follow your model just through text by reading it once so apologize if DR wasn’t the reason.
