Yeah, I do as you telling me . And ..... 

*** Error 20393 (STR+393)

Hi @Aurora!

if i were you i would do a small test-task with only connector in ls prepost. you can see how it works and redo it in HM.

another way, if you use rigid bodys in ls dyna, you can not connect it by rbe2 instead you should use extra nodes set.=)

Hi,

if the component is RIGID, please use XtraNodes to connect the comp with the joint's nodes
