How to compute correctly the heat flux in order to obtain a stable thermal/thermo-hydraulic coupled simulation ?

Dear all, I am trying to couple a simulation with two codes, say code A and code B (different discretizations). For code A we solve simply the conduction equation (solid), while in B we solve the...
