Sir I mean that I am having a "round cross section beam" which is simply supported (i.e fixed support at one end and displacement at other end ) having force at the center ( at mid point ) on top surface of the round 3d beam.

So my question is that how to apply this constraints of fixed support and displacement (i.e either on surface or edge or point) for simply supported beam. And how to apply force at the "mid point" of the outer surface of round beam.

I'm using ansys aim 18.1
