I want to simulate a bent tube in ABAQUS with continuous linear function thickness and diameter variations from one end to the other. To help you comprehend the question, I’ve attachedĀ a sketch.
Mesh definition, surface definition, and boundary condition specification are crucial since later on I want to hydroform it into an even more intricate shape. For modeling programs like SolidWorks, CATIA, or ProE, it is not a problem, but importing parts from them is a mess. Even if the import is somehow successful, meshing, surface interaction definition, and BC defining are challenges. Therefore it would be fantastic if I could directly simulate it in ABAQUS.

I attempted to use the 3D/Shell deformable sweep command, but it just requested a sweep geometry and then continuously swept the geometry along the stated path, when I wanted to linearly alter the thickness and diameter.
Is it possible to carry it out?

Hi,

You should write a Python script to sweep this or create any other geometry that has something like this. If you need any tutorial videos for scripting, I suggest checking the link below. It will help you with your current problem and future as well.
