Infinite swept wing problem

[S5331107]

Hello everyone!

I am attempting to analyze an infinite swept-wing problem using ADFlow, but I have encountered some issues. I kindly request your suggestions to overcome these challenges. My approach involves studying the infinite problem by focusing on a small case with minimal dimensions in the spanwise direction to avoid long-running times. For this, I need to implement the appropriate boundary conditions, namely periodic boundary conditions. It appears to be impossible for me to implement periodic boundary conditions in the ADFlow code. Has anyone successfully managed a similar case? Could you please provide guidance on how to execute such a case? Specifically, I am conducting a simulation with a NACA 0012 airfoil, and the mesh (in .cgns extension file format) has only one cell in the spanwise direction, considering Euler equations.

I've attempted to use the "beta" variable (side-slip angle) to simulate the swept problem, but the outcome data doesn't match the results obtained with another solver where it's possible to specify the swept angle. The issue is very likely related to the boundary conditions and span mesh dimension I am using (Symmetry BC, 1 cell in the span direction), but as mentioned earlier, I would like to use the smallest mesh possible.
