Can 2 rigids have the same dependent nodes?

RodrigoFST_22268

I'm doing an optimization to a rim centre. I defined multiple nodes to simulate different points of the contact patch. I connected the nodes with the washer area using rigids (RBE2) elements.

 

The problem is that when I run OptiStruct it gives the error #723. After some research I saw that it's because different rigid elements have the same dependent nodes. However I need them to have the same dependent nodes.

 

How can I connect the different nodes to the same area without having this problem?

 

Thanks!

Hi,

 

Maybe with coincident nodes you can connect but to understand the problem, can you share the model file please?
