Hello i have an eye model. inside the model there is a fluid region for the image is empty region and i use fluid solid interface. for fixed support like second image. part for fluid is suppress in mechancial but in fluent i set to system coupling and define as fluid. but when i simulate with concentrate force at top of model it not distribute any force or pressure?. is it wrong boundary condition or lack of boundary or anything else?

I suggest you run the model entirely in Mechanical. You don't need Fluent to represent fluid in a closed cavity in Mechanical.  See this discussion.

but how to add fluid property if ansys mechanical required elasticity? because when i run solver mechanical, it cant solve because need elasticity property

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.
