Hi All, I am creating two 2d zones (fluid 1 and fluid 2) with a common boundary line. By default, fluent should consider this common boundary line as ineterior, unfortunately is is considering this as a "wall". Can any one suggest how to overcome this prob?

So far I remember, this was not a prob earlier.

Is it a multiphase problem? Did you specify a multiphase model in Fluent? If not, your problem is logic: Fluent cannot handle an interior between two different phases without a multiphase model selected.

If you really need an interior, check the geometry in Gambit. Is your geometry connected?
