ystar and yplus
 

Dear all,

We all know they are different, although they are close to each other in equalibrium flow. My quesion is how the fluent calculate the yplus and ystar? Actually when I calculate the flow where separation phenomena exist, the y+ value is still not zero. Could any one help to figure it out?

thanks sarah

Hai Dear,

First of all, I am having doubt on the importance on ystar and yplus.
