solid-solid interface

Hi all,

i am having problems with my mesh. I am modelling an aerofoil in transonic flow. What i have is an aerofoil(solid zone) and an additional piece of mesh attached to it (also solid zone). However the attached piece of mesh is not conected along its entire length, sort of,

| what would be the aerofoil |

but when i solve the flow the solution diverges due to the energy. i have tried labelling each part individual as a wall so that i have coupled heat transfer but this does not work! any ideas?

Many thanks,

Greg

p.s. if the aerofoil and additional mesh is combined into one solid zone the solution will converge.
