Dear Foamers,

I've computed y+ for an LES case (flat channel) with the functionObject type yPlusLES during runtime and, after the computation has finished, with utility yPlusLES. The graphs (plot over line) show y+ values in spanwise (z) direction of the channel.

The first picture shows the results of yPlusLES utility, yPlusLES function Object and y+ computed with class wallDistData for mesh1:

wallDistData<wallPointData<scalar> > y_(mesh, uTau, true);
yPlus = y_*(y_.data()/nuLam);

First picture --> mesh: y-direction, height = 1m, # of cells = 50, mesh refinement (1 2 1)
Second picture --> mesh: y-direction, height = 1m, # of cells = 100, mesh refinement (1 2 1)
Third picture --> mesh: y-direction, height = 1m, # of cells = 150, mesh refinement (1 2 1)

I've assumed that yPlusLES utility and yPlusLES function object imply the same method. The data basis is the same. I don't understand why there is a difference between the results of the two methods.
Why decreases the difference between y+ values of the two methods if I increase the mesh resolution?

Class wallDistData:

Foam::wallDistData<TransferType>::wallDistData

Are there other options for TransferType beside wallPointData. I've expected the same result for y+ by using wallDistData class, too.
