Ansys combi 165 rotational spring/damper modelation problem

Ansys combi 165 rotational spring/damper modelation problem

Ansys combi 165 rotational spring/damper modelation problem

(OP)
Good day,

I'm trying to model a viaduct in Ansys Inc. with Ls-Dyna, explicit dynamics. I'm having problems with the rotational spring dampers. Ls-Dyna says that I must define an orientation vector but I don't know how to do it in Ansys. I've searched through all the web and the only thing that apparently I must declare when using a rotational spring/damper is the keyopt(1)=1.
Please help me, I really need to get this job done.

Best regards
Andre Jesus
