Y+ Calculator

Y+ Calculator


Y+ Calculator is a handy tool for calculating the grid spacing at a wall to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations. Simply specify the flow conditions, the desired y+ value, and compute your grid spacing.

If you are an engineer running viscous CFD computations, achieving a target value for y+ in your grid is essential for both resolved and wall function grids for accurate results. Save time by computing your near-wall cell height for the boundary layer before generating your grid.

The Y+ Calculator works in either SI or Imperial units and quickly resets to sea level conditions.

This utility is brought to you by Pointwise. Reliable people. Reliable tools. Reliable CFD meshing.

Note: Computations are based on flat-plate boundary layer theory from Frank M. White’s Fluid Mechanics 5th edition, page 467.
