Mesh near wall is very critical to capture boundary layer physics in CFD. This Y Plus / Y+ calculator gives first mesh cell height required for desired Y+ value selected based on turbulence model wall treatment.

This Y plus calculator gives first cell / grid height based on input values of free stream velocity, density and viscosity of working fluid, and a reference length. The desired wall Y+ value in the solution. These calculations are based on flat-plate boundary layer theory.

When modelling turbulent flows in CFD, turbulence models require the specification of turbulence variable values at the inlet boundaries. There are several ways to provide turbulence parameters at boundaries. This calculator gives all the turbulence values based on inlet conditions like velocity or mass flow rate, inlet area and fluid properties. It calculates all turbulence values like Turbulent Kinetic Energy (), Turbulent Dissipation (), Specific Rate of Dissipation (), Turbulent Viscosity Ratio (), Turbulence Intensity () and Turbulence Length Scale ().
