Add a moment to the top of a 3D cylinder

Hi jiadong.wang,

Please can you share your model.

Thank you

Hello,

 

I'm trying to do a simulation with HyperMesh on a cylinder with the bottom fixed and a axial moment on the top.

As suggested, I create a node in the middle of the top surface of cylinder and use RBE3 to tie the node and every node of the top surface together with dof123456 activated. Then I apply a axial moment on the node I created. But the simulation doesn't work: there is only a disk in the result.

When I change the moment in to a normal force, it works, so I think the problem lies in the moment.

Could you help me?

 

Thanks!!

Can you constrain the Y translational and release the rotation and check the results?
