slek is on a distinguished road

my model is a rectangle and the bc's should be taken as convection at left,right,bottom and top of my model.I have used udf for the top BC to give energy source when the laser comes in contact wid the rectangular block. but i also want to give convection for the top BC where the laser dont come in contact. How can i do that??

I have tried naming the wall twice in gambit but it shows error when i export so i think i cant duplicate the walls...

Please help me..I need it soon..
