Hello everyone.
I'm simulating a solid object impacting a beam mesh in LS-Dyna ACT (Workbench).
How do I connect the beam elements into a single mesh with a contact?
I've tried multiple contacts, but nothing works:

Please help. Thank you.

Hello Javat,

Please use CONTACT_AUTOMATIC_BEAMS_TO_SURFACE , and use part Ids for slave and master side, this should work.

Thanks,

Vijay

Thank you for your reply, sir. But I need it to be something like a bonded contact, so the mesh is firmly secured.

If these line bodies were converted to beams in SpaceClaim, I suggest you use the Share button on the Workbench tab to cause each intersection of two lines to share a common node to tie the mesh together.

Yes, of course sir, I did that, but how do I set up the contact in the mechanics section later?

[javat33489]

Yes, sir, you're right. I misunderstood you at first. I was previously hesitant to press "Apply" when I was making a sphere in Spacecraft.
Now everything works, all the beams have become a single mesh body.
