Need suggestions on what boundary conditions should I use to capture the change in the length of stent when the internal pressure is applied. I keep getting errors when I am trying to keep both the ends of the model free , citing problems with DOF.</P> Thu, 23 Mar 2023 05:45:43 GMT roy.priyanshughost 2023-03-23T05:45:43Z Simulating a radial expansion https://forums.autodesk.com/t5/fusion-design-validate-document/simulating-a-radial-expansion/m-p/11841120#M42403 <P>I am working on the design of a cardiovascular stent and am facing difficulty in simulating the radial expansion of the stent with the application of an internal pressure.
