i have a case flow inside tube and outside it
internal flow is laminar and external is turbulent so how can i define this problem in fluent as it accept one model only
thanks for your interest

In cell zones condition, there is a check box for laminar zone. This allows you to specify a zone as laminar and still use a turbulence model for other zones. So use a turbulence model, and specify the zone as laminar.
