In this video you will learn what y+ values are, how to mesh prism layers for effective y+ values, and why y+ values are important in simulations. You will more specifically learn how to:
Describe the basics of law of the wall and y+
Change mesh parameters: prism layer stretching, prism layer thickness, and number of prism layers – and see how it effects wall y+ values
Identify types of simulations where y+ is/is not important
