Depending heavily on the problem description and the main quantity solution based on, the k-e model is influenced by the user to capture the phisical phonomena. heat transfer problems, high mach numbers with thin attached layers, low mach number with separations and heavy back flows ...etc. alle these different combinations requires an experimented user to define the priority and the solution dependency value.
