What do you mean by "using it in simulation software"?

I think you need to make it clearer what you are trying to do. Then i will be able to give you some advice.

I'm not sure how the parts are physically connected to each other, but for your static case you could use boolean commands to merge your solids into a single entity, and then mesh. Your mesh looks pretty poor though, you will need a great deal more elements. You could also model and mesh the items separately and have relevent connector elements between them (RBE'S, CELAS etc) depending upon what best fits. You can also imprint your mesh onto the other item so in effect you could have coincident nodes.
