Hi all! I am working on a RANS simulations of a turbulent BL over a homogeneously rough wall. I wanted to ask if anybody knew of a way to directly extract/write the KsPlus computed by the wall function so that it's then possible to directly sample the value from the controlDict. I am having troubles understanding the difference between the various categories of scalars in OpenFOAM and I get millions of errors when I try doing it on my own. Any help is appreciated! Thanks in advance

Not sure.

Adapt function object for writing yPlus (see e.g. https://develop.openfoam.com/Develop.../yPlus/yPlus.C) to write KsPlus instead?

Hi! Thank you for your reply! I thought of doing that but I wanted to check if there was a way of extracting it at every iteration from the wall function directly before I do that
