Y+ is zero, why?
 

Hello,

I have a question about Y+.

I'm checking it on this part of my geomtry (the part of the wall where the circle is, purple color) :

Here is my Y+ on this wall :

I don't understand why he goes to 0? Can someone explain me why?

Thanks for your help.

hi!
I don't think that your y+ is zero, it is just too small to see it in the diagram. If the maximun value of y+ was 0,1 for example, you could better see what now seems to be zero.
