Hello folks,

I've read probably a dozen threads on using low-Re kwSST (no wall function) and have a mixed bag of results. Honestly after so much information and trying to figure out what goes with what version and what may have changed...I'm lost.

It appears Henry himself said several years ago if you use a specific combination of wall functions for nut and k, you can integrate to the wall (http://www.openfoam.org/mantisbt/view.php?id=179#c351), but it isn't specified what to do for omega? And I'm not really sure what he means by 'continuous' wall function.

However, it appears on the UNIGE training course that you can just specify k and w as fixed small values. This would seem to me to be saying kwSST does include the damping functions...but who better to say this than Weller? This training is newer than Weller's comment, though.

I have some follow up questions that are minorly related:

1. Why are OpenFOAM's wall treatment models nearly universally called 'wallFunction' ? In every other code and academics 'Wall function' is exclusively reserved for modelling the log layer and nothing lower, whereas here we have 'low-Re' wall functions? Every other person I've heard refer to this as a 'wall treatment' or 'wall integration' instead to be precise. Is there something I'm missing, or is it just OpenFOAM's convention?

2. I'm still trying to get used to reading the source code, but it's very hard and not commented the greatest. The doxygen HTML output has some insight, but it only seems to cover post-processing and boundary conditions. Did I miss something or is the rest of the documentation for solvers, schemes, etc available in the HTML format? Is doxygen more complex and I just don't know how to use it to see the rest?
