How to model the case of horizontal directional drilling on a pipe ?

      Hi

      I am currently tasked with modeling the stresses that occur when pulling a pipe in Horizontal directional drilling. But I'm confused, how to model it in ANSYS. I appreciate if anyone tries to help me.

      The detail of this modeling is that I want to know the stress that occurs when the pipe is pulled from the ground to the bottom then to the ground again (the illustration can be seen in the image below). The pipe I am modeling has a diameter of 20 in and the hole in the ground is 30 in. When withdrawing, in the hole there is water that fills it.

      The second modeling aims to determine the stress during the operating mode of the pipe that has been installed in such conditions.

      Thank you for your attention

      Can you share a snapshot of the setup you have? If you have not started the modeling process then you can model the pipes, pulleys (with a revolute joint) , frictional contact between pipe and pulley and then apply the force/displacement.
