Hello Rana,


I am a beginner with CFD, so wait for confirmation from a CFD expert member, but from what I have read, you can use a Multiphase VOF model for your retaining wall fsi 02 Workbench project.



 When you do this, you create a domain large enough for both water and air to exist, and Fluent computes which cells contain 100% air, 100% water or a fraction of each at the free surface, which can change with time.


Raef Kobeissi has an example of a transient structural with a water free surface.

Note to readers with the Student license: 2-way FSI such as the above example, requires System Coupling, which is not included in  the Student license.
