How to set a mass-in-flow inlet at the middle of the model

Hello, everyone. This my 2d bubbling fluidzed bed model. When I try to set a mass-in-flow inlet at the middle of the left wall, errors are reported like this.

So how to deal with these error?

did you try setting zmax to 0?

Thank you for reply. I try it, and errors still exist. Do you have any other suggestion?

What is your cell size in y direction?
Try to make the inlet height equal to cell size or multiple cell size.

Thanks a lot! Errors disappear after I set the inlet height equal to cell size in y direction.
