Help with checking y+

Project Support
1

Hi, I have been very confused about y+ and seem to understand very little about it. In my simulation of 50mph, I checked the y+ and everything was under 10? I am having a very hard time understanding how the y+ works and would appreciate some help with getting my y+ values correct. I need to know how to edit my boundary layers if the y+ isn’t correct and what y+ values I need?

thank you for your help,
Frank Lucci

Hello!

The formulae are posted in this forum thread - there you will also find links to calculators available online.

As a general recommendation, I’d suggest that you make your own spreadsheet. This YouTube video is also a very good starting point.

Cheers

I would like to add a couple of documentation pages here that have valuable information:
