Reply To: How to model closed fluid cavity use FSI

Hi

See here for more info on how to use these elements inside mechanical (not natively exposed and not easy to use and requires APDL knowledge, so they are advanced). So first of all you do not need to model the interior gas/fluid volume. The below elements do not need that. See here for more info and details.

Perhaps other members can help more here if needed.

Hope the above link helps.
