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 Cadence Design Systems.

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