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

    Thanks Ken.
    In that example SOL400 is used and a contact. Because I don`t have SOL400 I should replace this with linear gaps or linear contact otherwise the two plates can "go through" eachother. But if there is a big assembly (so a lot of prestressed bolts) can one also model this with a couple of runs?
    And another question is: if like you said the SOLID bolt is replaced by a beam, this should be one beam and only two rigids? So a rigid in the topplate and a rigid at the small plate connected with a beam?
    Thanks
