I'm new to ANSYS and I'd like to simulate a ballon containing water in ANSYS.
The ballon is set as shell and the water is static. External load on ballon will arise the hydrostatic pressure on the ballon?
I've finished modelling the ballon but I don'w know how to simulate the static water. Please help.

Thank you for your reply. You mentioned that acoustic analysis worked when the boundary is rigid. However, my ballon is very flexible and during my simulation, it will have a large deformation.I don't know if acoustic analysis would work, but i'll have a try.
Thank you again for your excellent suggestion!
Huiming Pan Hi you can just create empty volume (shape according to balloon) , then consider the fluid inside the volume or balloon in boundary conditions. The surface of balloon you can assume as structural part.

Abdul Gaphur Thank you for your reply. I recently found a solution using hydrostatic element HSFLD242 for 3D and HSFLD241 for 2D. It could be useful just by defining an inner face on which the fulid has a hydrostatic pressure.
I refer the blog in https://simutechgroup.com/contained-fluid-in-mechanical-fea-model-working-with-hsfld242-elements/
