Reynolds Stress Model in Fluent Vs CFX

Tim

Hi.. I currently have access to both CFX & Fluent 6. I've done some simulation in CFX5.7.1 before and wish to compare the same model in Fluent. CFX5.7.1 has a range of Reynodls Stress Model:

1.SSG model developed by Speziale,Sarkar & Gatski, 2.LRR-IP (isotropisation for production) & -QI (Quasi-Isotropic) developed by Launder,Reece & Rodi 3.Baseline omega model 4.omega-Reynolds Stress model

From what I read from Fluent manual, Reynolds stress model used in Fluent 6 is developed by Gibson & Launder, Launder, and Launder et al. Does anyone know if the model is the same as LRR-IP or LRR-QI used in CFX?

Thanks for your information. Cheers,Tim
