This is probably not the simplest thing to start on during a trial. I would recommend a tet mesh here, unless you absolutely needed the hex accuracy. Another alternative that gains accuracy but removes complexity is axisymmetric modeling. But that's not what you asked, so here's what I did for your geometry:
You'll notice that this was a mix of Femap commands for manual and automatic hex meshing. This isn't the complete job, but you can continue with the method to achieve what you're after.
Best of luck!
