Hi,

I am a new user of Hypermesh, I have to link two RBE2 in a node, and let the relative rotation between the two rigids. but the message error that the program displays is :

 

' *** ERROR # 723 ***
 An invalid rigid element.
 This RBE2 is not connected with any structural element.
     RBE2 element id = 399563
 independent grid id = 437040
 Note: If this rigid element is also connected with other rigid elements,
 then this error means that there is rigid body mode or mechanism remained
 in this rigid element chain due to lack of connected structural elements.'

 

How can I link the rigids with the relative rotation in a specific node?

thanks
