How I calculate previously the y+ value.
 

Hello,

I want to define well the mesh of a fluid that is running into a pipe. But I have doubts about how to define the boundery layer (thickness, quantity of layers). I know that it can be well defined by the y+, but how can I calculate it? How can I define also a good expasion factor.

Thanks in advance, Claudinei
