Environment information

** OpenFOAM version :** v2012|v1706 Operating system : ubuntu 1804 ** Solver:** rhoCentralFoam

I have calculated the laminar flow , transition flow and turbulent flow cases. The model is k−ωSSTLM and k−ωSST, respectively. The yplus no more than 1 near the wall. And the wall parameter oscillation phenomenon appears in all cases.

About the choice of limiter, I also tried many options. The divSchemes has no obvious influence on this phenomenon.

But when I use commercial software to calculate under the same boundary conditions and mesh, there is no such phenomenon. This makes me very confused.
