Altair EmployeeHi,
bind each triple nodes by 1d>rigids, don't forget to bind them with regarding component, too
Yeah, I do as you telling me . And .....
*** Error 20393 (STR+393)
Nodal rigid body ID 19 contains node ID 123414
already used in a rigid body/nodal rigid body definition.
Altair EmployeeHi @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.=)
