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.

Missing info

This is not really useful without telling the user what correlation is used for the skin friction coefficient ( flat plate, internal flow, etc.) and it is also not user friendly to leave us to guess (or do our own hand calculation to check in which case what is the point of having an app, really) whether the reported wall spacing is the physical distance from the wall or the mesh cell thickness. I have not opened this app in a long while. I don’t remember it being this way before, although maybe it was.
