Flow behaving strange #4
Description
Hi @rybchuk ,
I hope you are doing great. I wanted to discuss a problem which I am facing. i think it is flow reversal.
https://github.com/rybchuk/amr-wind-tutorial/blob/main/03_turbines.md, here you explained that if the inflow is aligned in x direction purely, the "both the ylo and the yhi planes in the precursor simulation. Sometimes running with ylo isn't enough because a small amount of flow can enter the domain through yhi. This scenario can manifest as a simultion with a growing CFL error."
I have tried previously also saving the precursor files in yhi too, but right now I did not save in yhi. I am attaching some plots, can you confirm you were referencing to this behavior of flow at (x output).
I am attaching the input files too.

P.S, I have asked at lawrence's github issue board too, since you mention this issue in your tutorial I really wanted to get help from you also. Thank you
