Hello,

I am very new to Hypermesh and I am trying to add a Seam Weld Connector in my project.

My Proplem ist, that every created RBAR node is free and not properly connected.

When I try to export the file to Optistruct for a analysis I get the error 722.

*** ERROR # 722 ***
  An invalid rigid element.
  This RBAR is not connected with any structural element.
      RBAR element id = 793026
  independent grid id = 158219
    dependent grid id = 158220
  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.

Can someone help me to fix this problem?

Thank you!
