Dear all,

for some time already I struggle a lot with trial to implement the turbulence model from the title.

Basing on those two sources:

and of course original model: A robust k − ε − v2/k elliptic blending turbulence model with improved predictions in near-wall, separated and buoyant flows

I based my files on original v2-f (that's the reason for unchanged variables k,e,v2,f). I was able to write and compile it, however turbulence kinetic energy results obtained even with the flat channel flow are wrong.

In the attachments, I inlclude all the files, including wall function for modified epsilon.

Therefore my question is, has anyone succefully implemented the same model? Or maybe someone can identify, what I am doing wrong. Maybe I shouldn't base it on original v2-f?

I guess you forgot to attach the files ...
