Thank you @negativevolume It was for one month ago. As I couldn't do that I solved the problem by a rigid part around the disk. But my curiosity ...

Well done.

I know how to plot force-time graph but about p-t I have no idea.

@sheida No need to think complexly. Point 6 is your residual velocity.  Screenshot_59.png

@sheida I want to answer to your second question. To see residual velocity it is very easy. Follow this pic's steps:  Screenshot_44.png

No problem @negativevolume Yes I have been trying but not for enough time. After a few milliseconds it stops. which method you suggest? LBE, ALE?...

Hi @negativevolume Do you know how it is possible?

@negativevolume thank you. I am not sure about what you mean by "level of consistency" but I know Normal vectors of the both tubes are towards axis ...

Thank you @negativevolume. I know what you mean. I don't have shared nodes. Actually after design structure I copy elements of connecting rings to the...

dear @negativevolume I created a new topic at:

As you see, the Young Modulus gives around 16 MPa by pic below: But he claimed that is 210 MPa. (of course for steel it is about this value ) Wher...
