Y plus problem

lehoanganh07 · January 11, 2014, 03:30

Dear fluent user,

I am using k-epsilon with wall function. This is my result of y plus which is between less than 1 to 12. So I thing it is wrong be cause in the Fluent guid, It said that Y+ must be between 30 and 200.

So do I need to remesh to increase Y+?

Thank you very much

This is the link of result, I cant post in forum

Yes , if you prefer to stick with the wall functions you need to remesh your model to get the y+ values higher than 30.

Good luck
