I am trying to do a static analysis. What I want to do is to calculate the moment on the top of the transition piece. I have calculated the value of the moment and what I think that I can do for the simulation is to apply the force on the inner edge of the central tube as you can see in the picture below.
1) Do you think that it is the right approach to calculate the moment?
2) How I can make it in order not apply the force to the total surface and only to the edge and to the right direction?
Thank you very much in advance. If you need any further details or the file feel free to ask.
