Dear all,

I know that we can get the value of yPlus through the function of -postProcess, but how can I get it when using yPlus as a parameter in the programming.

I tried with lookupObject, it does not work because OpenFoam does not output yPlus. Does anyone know what function should I use?

Many thanks for any help.

Regards,

Maria

I assume, you want to use yPlus in a model or solver of yours.

The epsilonWallFunction computes yPlus in the following manner:

const scalar yPlus = Cmu25*y[facei]*sqrt(k[celli])/nuw[facei];

The near wall distance y is available through the turbulenceModel, k and nu are available as well.

Many thanks. I will try.
