Application to Couette Flow with Bubbles

[gortali]

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!

Hi @gortali What if we use rigid particles and move it at a constant velocity so it modeled the same way as in the DEM or MPM...that's one possible solution I can think of...
