Good afternoon. How to use Constrained_extra_nodes in WORKBENCH LS-DYNA? Will it be a snippet? Tell me please.

You can use LSDYNA Pre > Rigid Body Tools > Rigid Body Additional Nodes.

its not work
This Field is only available for Rigid Bodies : Rigid Body Additional Nodes
Because this part is not rigid

The keyword *CONSTRAINED_EXTRA_NODES only works with a rigid body. This keyword is used to add nodes from a flexible body to a rigid body. This effectively connects the nodes from the flexible body to a rigid body. If you don't have a rigid body, this keyword will not work. Here is more information from the LS-DYNA user manual:
If you want to connect 2 flexible bodies together, you can use a bonded contact (tied contact), use spotwelds, have a node to node connection via the mesh, or use joints. There might be other ways that I don't think of riight now.
Let me know how it goes.
