i have to study the heat exchange inside the radiator of the car. i need to use the dual cell method because i have two flows that goes into the radiator. on the left you can see the direction of the auxiliary fluid (water) and on the righ the direction of the primary fluid (air).

my doubt is about the meshes, i'm used to open up the fisrt file on fluent which is the domain plus the radiaor with the air mesh, and the with the command:

/mesh/modify-zones/append-mesh

i'm able to import the second mesh for the auxiliary fluid. but i've seen that i could also use this command:

/define/boundary-conditions/modify-zones/copy-move-cell-zone

that makes an dual of the cell zone selected. and as last thing i don't know if i have to use the interface or not. Please don't answer me with 'read the ansys guide' or with some link. i already read everything about this and they don't explain nothing about the meshes how it should be. 

thanks
