Bolt with both constraints and force

Hi there,

I'm wondering what's the best way to model a bolt in Hypermesh considering that it's constraining the model and also has the bolt tension force applies.

If I model it the usual way, with RBE2 elements, and constrain the center node, I can't apply a force to this node because it won't do nothing (it's displacement is equal to 0, the analysis is linear with [K]{u}={F}).

I've searched this topic online and didn't find anything using a bolt both to constraint and apply a force. Should I use the wsher area to apply the force and the edge nodes connected to a RBE2 and constrained in the center node?

I'm modeling a wheel. I have the forces applied in a node simulating the contact patch and connected to the wheel using RBE3 elements and constraints in the bolts connecting to the hub. I'm trying to find the best way of applying the bolt tightening forces to the model.

Thanks a lot,
