We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Thanks for your answer, 

Can you explain why the cylindirical support doesn't work in my case? As i mentioned I tried all the combinations for cylindirical support options (tangential-radial-axial free/fixed).

I did try your suggestons but dummy component (adding/drawing another flange) is not allowed, also can you explain remote displacement part a bit more in detail. Because i did try remote displacemenet as: 1)Select 4 boltholes inner surfaces(as it's shown in my figure above), 2)insert remote displacement, 3)behavior = deformable and 4)set the all six DOF to 0. 

But the point is once i tried with only one bolthole instead 4 boltholes results were same but constraint was changed. So it's impossible.

Second thing is, do you suggest that path: 1) Select 4 boltholes inner surfaces, insert remote displacement (this time placing remote displacement x-y-z coordinates due to dummy flange component back side(opposite side due to contact surface).(dummy flange which is not necessarily dwarn in this case) )
