1) I have did mesh refine by using proximity and curvature and used mesh convergence tools to get a very refined mesh. I am plotting max shear stress because I am following that theory to decide my FOS.
2) Yes my max stress is at the bolting points which I got from hyperworks. That means I cant use remote force at that location? Can you explain me why is that so?
3) I have tried using the remote force on simple objects. From the results I came to know that remote force is applying an additional torque on the object and that is the reason I guess my result is very high.
