Hello everyone,
I am modeling an axisymmetric jet impingement case with 9 jets in an array directly above a heated plate. The plate receives heat flux from the bottom face and the top face is the face which is interacting with the fluid from the jets and ambient as well... What I did is:-
1) Read case file for Domain and Plate Separately.(Append both files i mean to say)

2) Then i selected the solver settings to be used and the boundary conditions too

3) I selected interface as the boundary condition for the domain face and the plate face that are overlapping each other.In Grid interface settings, i connected these faces too

4) Problem is that if now the wall or top face remains as interface then how will i input the boundary conditions i need top give there....
Secondly even if i forcefully change it into wall later then i could not plot temperature contours at the interface.... Help please....
