Y+ Calculator vs sci.calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Y+ Calculator
This app calculates the necessary grid spacing for computational fluid dynamics (CFD) simulations. It helps engineers determine near-wall cell height for accurate viscous flow computations. Supports both SI and Imperial units.
- Calculate grid spacing for target y+ values
- Supports viscous CFD computations
- Works in SI or Imperial units
- Resets to sea-level conditions
- Based on established fluid mechanics theory

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.

Verdict
The clearest difference is in-app purchases: Y+ Calculator at none against sci.calculator's 1. Y+ Calculator also leads on iOS requirement (9.0 vs 15.0). sci.calculator's advantage is update cadence (every 5 weeks vs every 8 months). On price, ads and device support there is nothing between them.
