Hello,


I am experiencing an issue with one of the OpenFOAM tutorials titled "bubblepipe." In this tutorial, it assumes a vertical pipe. However, I have modified the gravity direction from z to y while keeping other parameters the same. Unfortunately, the simulation crashes. Specifically, it runs smoothly until the gas (bubbles) reaches the pipe's outlet, at which point it crashes. I would greatly appreciate any insights or ideas you may have regarding this problem.


Thank you!
