Application to Couette Flow with Bubbles

Hello,

I am interested in applying the GNS method to my dataset, which involves a Couette-type flow with droplets. Specifically, I intend to treat the droplets as the nodes in the GNS and predict their acceleration. However, there are a few modifications I need to implement, specifically regarding boundary conditions:
- The top and bottom walls are moving, simulating the Couette flow.
- The left and right boundaries should be periodic.

Could you please advise on how best to modify the current framework to accommodate these boundary conditions? Any guidance or suggestions would be greatly appreciated.

Thank you!

No file, test, or entry point is identified. Start by reviewing the GNS framework's current boundary-condition handling and the path that predicts droplet acceleration, then determine how moving top and bottom walls and periodic left and right boundaries should be represented for the Couette-flow dataset.
