Modeling of Bolts

ron.kunz
Dear all,
I have a big assembly and want to model bolts in the complete assembly. What is the best and accurate way to model this.
Cbar analysis is accurate enough to analyse the bolt forces. Boltstress is of secundair interest.
Are there examples for these bolts?
In addition bar orientation for this CBAR property, how can this best be modeled?
 
Thanks in advance

    I have created a model of a solid plate with a hole and with rbe2 utility and added a bar with properties of M12. No pretension added. When I add a force of 9kN to the centerpoint of the spider to simulate a tension and analyse the model I get for the axial force a value of 1620N. I would expect the axial force equal to the force I have specified?
