Hi everyone

I simulated a case in wich I have a wall with a heat flux (q=2000 W/m2) using pimpleFoam, I fix a boundary condition as a fixGradient in the next way:

 plate
    {
        type fixedGradient; //fixed heat flux b.c.
        gradient uniform 2000;

    }

I postprocesed the data using Plot over Line in Paraview so as to get h (convective coefficient), I extract the T_i results and then I calculate h=q/(T_inf-T_i). My question is, It possible to calculate in that way? or I should have to calcule with other stepts or in other way, because when I calculate that I get some results (figure 1) arround 20 times the expected value. (figure 2).

It is correct to used that boundary in a scalar transport temperature file in that way? Thanks
