Free body force function

We like to obtain the forces at a lug of a pressure vessel. However we do not restrain the vessel at the lug but still need to obtain forces at the lug due to internal design pressure etc. The free body function seems to be the way to go but it gives us a force of zero.

Please explain how this function works and if there is other way to obtain the forces?
