Non-Reflecting Boundaries with CEL

Hi dear community,

I am currently working on modeling the interaction between water waves and a cylindrical breakwater using the CEL technique in Abaqus.
To ensure realistic wave behavior, I would like to minimize — or ideally eliminate — wave reflections at the boundaries of the Eulerian domain.

Unfortunately, my attempts to implement the built-in Eulerian non-reflecting boundary conditions have not been successful so far.

I would greatly appreciate any ideas, hints, or suggestions that could help me achieve this.

Thank you very much in advance!
