switching Off and On wallReflection im modified LRR

Hi FOAMers!
Does anybody have experience with modification LRR turbulence model? I modified the model and I am facing inability of new turbulence model in switching off and on the wallReflection ! Is it coming from compiling?
Any help could be useful.
Best Regards Sina

Hi, I meet a similar problem recently. I found that the wall reflection term has a significant impact on the numerical stability, but I don't know the specific details of this term. For example, whether this term is considered in engineering application, or what are the requirements of LRR model for wall yplus? Are you willing to provide me with some help?
Thank you in advance!
