I have a problem with the coupling of a fluid in a steel structure.
In simple terms, I have a cavity filled with a fluid. The fluid can be considered as incompressible. The steel body experiences a load (external pressure), which causes a deformation of the steel body. The deformation causes a stress change / pressure change in the fluid, which I want to know.
What could be ways to solve this?
Remodel the fluid (without e-module) in engineering data? The steel body deforms elastically. For a static structural analysis I need elasticity.
a FSI in Fluent? What boundary conditions must be met for this? For example, there is no flow in the fluid.
I am grateful for any help!!

I created two geometries in SpaceClaim:
1.Solid (Steel) ÔÇô Main Body
2.Fluid (Water) - Cavity
Can I implement the property comment of a fluid (242) Workbench/Modell/Geometry? Right click on the specific geometry lets me insert an APDL Command window.
