But if mesh the inner box first and than other box latter fluent will treat the separating wall as interface but i want to set that as interior Thanks for the reply Srinivas

But if they are internal domains, you need to turn on an option... Just go into "Mesh (tab)=> Global Mesh Setup => Volume Meshing Parameters". Set the mesh method to "Quick (Delaunay)". Then go down in the DEZ (data entry zone) and turn on the option for "Mesh internal domains". You might also want to turn on "Flood fill after completion" while you are there...
