rotation fixture

Simulation Question: How can I fix a rotation of a plane, without fixing any translations.



A hollow cylinder static simulation. The faces of the hollow cylinder (or a part of a cone to be more precise) need to be fixed parallel, while a force is pushing on the side of the cylinder. I want to study the deformation of this cylinder.


What I did: Modeled a quart of the cylinder and put a roller slider fixture on all the sides. At one of the sides that cuts the cylinder a force is applied. This almost is what I want, but it prevents the cylinder from getting slightly longer, which caused unwanted stresses and behavior. Therefore I want one of the sliding fixtures to only keep the plane straight, but allows movement orthogonal to this plane. In the figure I've attached to this post: The sliding fixture at the left (or right) must allow axial movement, but keep the plane straight and still allowing the round shape to become an oval shape because of the force.cylinderquestion.png
