Hello,
I am new to openFoam and C++ .I want to implement the convection B.C. in chtMultirigionFoam(solver for conjugate problems) for a wall.

for this purpose i have used energy balance and with Considering the convection BC i have found following equation:

Ts= c1*(c2* Ta+Ti )

In this equation Ts is the temperature of the boundary and Ta is the ambient temperature and Ti is the internal adjacent cell centers temperature(internal adjacent cells centers which are next to the boundary) and c1 and c2 are constant.
now i do not know how i can find Ti and how i should define it here( Ti is updated at each iteration) and how should i implement this B.C.?
