simply supported beam

Hi Panagiotis and Sawako,

thank you so much for your very interesting plug-in that I'm going to study.

As first test, I'm tryng to simulate the behaviour of a simply supported beam (pinned - pinned). I imagine that the beam can rotate only around the y axis and I set the boundary conditions (for both endpoints) as follows:

The Frame Results component shows a strange (to me) result:

1) F0 and F1 are both: (0.0, 0.0, 0.0). Since the beam is vertically loaded (self-weight) it should appear a z component (Shear Force).

2) M0 and M1 show a y component! According to the boundary conditions (beam can rotate only around Y axis) the bending moment should be null.

Please can you give me some clarification? Probably is a setting error.

Thank you in advance,
Arturo
