Hello, I don’t know whether the error of the boundary condition is the setting error in the software or the error in the UDF. How should I solve it? Thank you!

The bottom_leftwall and bottom_rightwall regions go from y=ymin to y=ymax. I believe you meant them to go from y=ymin to y=ymin so they are planes at the bottom.
Yes, thank you for your answer
