I would like to model the inflation of balloon. This subject is of interest for the medical industry, but I am interested in a conventional party balloon (elastic, not the mylar type). Has anyone seen any information on this?
can't be done in flow simulation currently. you need a solution that includes FSI, fluid structure interaction.
but, if you don't care about the fluid problem, you could try setting it up as a nonlinear problem with an internal pressure where the pressure updates with deformation. the challenge would be the amount of deformation and the thinness of the part and getting the material properties right.
