Hello everyone,

I’m working on a simulation involving vacuum flow through a flexible hose rubber liner. My goal is to analyze how the rubber liner reacts to the vacuum flow. I would appreciate any suggestions or guidance on how to approach this simulation.

Thank you in advance for your help!

Strictly we can't model vacuum in the CFD tools as the continuity assumption isn't valid. Technically there'a also nothing to flow?  If you're looking at how a vacuum effects a hose shape I'd go with Mechanical and assign a pressure (force?) to the inner and outer walls. The Mechanical channel wil be able to give more comprehensive advice.
