How does gazebo handle damping in Joint::SetForce ?

edit

I'm using gazebo's API to apply force to a joint with a non-null damping coeficient (Defined in the SDF). Is it necessary to include the damping effect when I call the method SetForce() ?

e.g joint -> SetForce ( 0, effort - joint->GetDamping(0) * joint->GetVelocity(0))

Or does Gazebo handle the damping automatically and I don't have to include it?

e.g joint -> SetForce ( 0, effort )

Thanks
