I'm working on a student project at a university in Germany.
It's my task to create a fluid-structure interaction in Abaqus. I have to implement periodic boundary conditions in Abaqus-CFD.
How can these PBCs be created in Abaqus-CFD?
At the moment, I have no approach and I hope someone can help me!
The values for pressure and velocity have to be equal on the periodic surfaces.
I can select specific values by inlet/outlet but I can't select 'periodic'.
Is it possible to set the surfaces periodic on the input-file or how do you think I should proceed?
Or is it just not possible in Abaqus-CFD?
I hope my English is good enough.
Best regards from Germany

You should be able to define periodic data in Abaqus-CFD. Try searching for periodic data or amplitude curves in the User's Manual.
