How to bent pipe with comosmotion?

[ilhwa]

Hi all.
I have interested in cosmosmotion and want to see how to bent a piep or tube with motion.
aleady give constrains for moving other parts.
but never bent a pipe. pls show me how to.

Hi,
"bending a pipe" is impossible in Motion since it's a rigid-body dynamic simulator.
There still is a - very - complicated way to model it as a series of interconnected small elements linked together by systems of springs having very specific stiffnesses...

Thanks for your care...
But I have seen some motion avi file on other web.

I can understand coantrains for motion only.
It should be something for pipe bending..
any constrain for pipe, variable axis, 3d contact, action
force....and so on.

Hi,
sorry, I wasn't able to correctly display the movie, so I understood nothing.
Probably it's some new feature of the latest version of Motion, which I don't know.
I know that two or three years ago, the users' comunity was pushing hard in order to have at least some flex-body instruments to simulate ropes for example. Bending a pipe can be treted same as bending a rope around a pulley, only with a very higher stiffness...

Thank you so much.
I'll try to study more.
Have good day.

The animation that was in the link was actually done with SolidWorks Animator. There was no simulation or calculations done for this.

Thank You,
