boundary condiction
 

hi all,

i have a question : i have two volume of aria with a common surface, so this surface is connected, now i do to specificat that surface is internal or fluent see it automatically?
thank you

When you set the boundary conditions, set it as "interior" for that face. By the way, make sure that the volumes share the same face, as opposed to having two separate faces on top of each other. I've done that too many times...

If the 2 volumes are connected on this common surface, then gambit recognizes this one as interior automatically. So you don't need to set it in the BC panel
