what kind of results can be obtained with these elements except nodal displacements?
As far as I got it, U-beam doesn’t return internal forces (moments, etc)
PS: US3 shell is supported by CGX2.22. There is a good verification example: lin_stat_cooks_beam_128.inp . But U-beam is not visible, when I am trying to visualize it. Looks like, only *print card is working in this case.
