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
  • List some prism layer meshing rules of thumb
