HOW CAN WE APPLY TORQUE IN OPTISTRUCT

Hi Everyone.

I have need to apply 250 Nm torque on bolt hole of a component in optistruct solver but i am not aware to which load card is use to apply torque.

plz help me which card/load is use to apply torque in optistruct.

my unit system taken is=

Mass=tonne

Length=mm

Force=N (Newton)

so unit of torque is Nmm

250 Nm=250000 Nm.

so plz help me which load will be use to apply this torque in optistruct solver.

THANKS & REGARDS
