Ram Guest Posts: n/a	Dear All, I have two questions about zero equation hvac turbulence model in Fluent: 1. Since the turbulence viscosity is affected by the first grid size. What is the recommended value for that distance? 2. Is this turbulence model suitable for indoor air flow regimes (I mean natural convection)? Many thanks, Ram
