duplicate application moment flender/torcent (patran)

[GunMaker]

hello to all, I press that I just started using patran and are not very practical of fem analysis. I must simulate the onboard behaviour (section b) of the particular in the figure subjected to a torque and flender moment .
the particular is blocked in all directions on section a and such moments instead apply to section c.the model has already been meshato with solid elements tet10. I tried to simulate the torque/fleating moment in different ways but when I do the analysis I get as a result of shifts,tensions etc. 0 (as if the loads I go to apply do not apply them to the nodes of the elements but to an external geometry to the mesh). I'm obviously mistaken or unaware of something at the conceptual level.
How can I apply a torque/flective linear distribution on the face and how do you work in such cases?

thanks in advance for the answers :redface:

the simplest method is to connect all the knots of the face in question with a rbe2 (infinitely rigid) and then apply the pair to the central node of the beard. Be careful that in this way, the knots of the face connected with rbe are infinitely rigid and therefore do not take charge, the adjacent knots instead take a non real load as they are on the one hand connected to rigid elements and on the other no. If the point of analysis is far from the beard this is the best way.
otherwise you can create a field on a cylindrical reference system and apply a force where instead of the load put the field. In this way, more complicated, it simulates a force that varies in direction and intensity, so that it looks like a torque moment, null in the center and with the maximum at the end
