Using Calculix to model a rotatable joint

Using Calculix to model a rotatable joint

Using Calculix to model a rotatable joint

(OP)
I'm hoping someone can help me with modelling a rotatable joint in calculix. Imagine 2 bars bolted together in a cross shape, with the bars free to rotate on the bolt. That is the type of joint I am trying to model. Anything I have tried seems to just be the same as a rigid joint. Thanks in advance.

RE: Using Calculix to model a rotatable joint

Which type of elements do you use for these bars ? If you want to model them with solids then you could also include the simplified geometry of the bolt and apply contact. Otherwise, there are various options for simplified modeling of different types of joints. You can use beam elements and constraints to achieve similar effect.

I was trying beams and adjusting constraints but it didn't seem to make any difference. Any chance you could show me a simple working model? Thanks.
