Axisymmetric Analysis of a threaded connection

Axisymmetric Analysis of a threaded connection

Axisymmetric Analysis of a threaded connection

(OP)
Hi, I am having some problems with analysing a threaded connection, where the bolt is hollow. So far the setup is complete, but I can't find a way to put the BC and loads correct on the model. Please, can someone help out? I can send the files needed if anyone have a chance to help out..

RE: Axisymmetric Analysis of a threaded connection

(OP)
I did get the solution to converge once, but I still get a lot of error messages saying time increment is larger than expected, and I have set it to 1e-20, getting the solution to almost converge, but the error message is coming still. I would really like for someone to have a look at this, since I am doing several analysis with different load scenarios. Is there some way to calculate the time increment, or am I doing something else wrong?
