"Interface" boundary condition in gambit?
 

Hello
I serached User Guides of gambit but did not found any inforamation about "Interface" boundary type which is in "specify boundary types",can anybody tell me what is this boundary type and when we use it?
thanks

hi
when you have two fluid zone with non-conformal meshes, or when you want to model MRF or sliding mesh between a rotating and a stationary zone you should specify boundaries as interface.

true
like modeling a free surface

Interior B.C. or Interface B.C.
 

In modelling of mixer in fluent(using gambit as meshing software) should i use interior boundry condition or interface boundry condition between the moving fluid and stationary fluid in MRF model ?
