Mesh interface problem in 2D model
 

Iam working on biomass cookstove project in which i have modeled 2 different zones one for outer body and one for combustion chamber and so now i have to create mesh interfaces between these two zones at primary inlet but in ansys fluent the mesh interface option is diabled.

why do you want to make an interface? you wanna apply there boundary condition?

make these two zones as separated meshes, load them one by one, than create interface.
if you are working in workbench mesher you may simply put these zones into different parts (in geom module)

best regards

Hi Alexanderz
As air will pass from one zone to another one i want to give interface between the two zones to that air will pass from one zone to another zone , even though i have given separate boundary condition to different zones the mesh interface option is disabled in ANSYS fluent
