Additional turbulence models for FLUENT
 

Hi all, I'm wondering if anyone has implemented additional user-defined turbulence models in FLUENT? I'm specifically interested in finding (or possibly writing) a curvature-corrected Spalart-Allmaras model. I'd really appreciate everyone's two cents on user-defined turbulence models, and if anyone's willing to share one they've written, it would help me get started! Thanks
