hi all, I work for a packaging company and I am a new user. I need to model an aluminium can during the process. I already have a result with an empty can modeled as a shell, but I need it to be incompressible, as in the internal volume (liquid) doesn't change and will raise the pressure if the can is deformed. My question is, can I model the can as a volume made of a hyperelastic, barely rigid material for the liquid, and aluminium only on the shell?

thank you.
