Hello Everybody,

I want to solve a convective heat transfer model of an external wall as a volumetric heat source. With the present boundary condition of externalWallHeatFlux I can give the following input

myPatch
        {
            type            externalWallHeatFluxTemperature;
            kappa           fluidThermo;       // fluidThermo, solidThermo or
                                               // lookup
            q               uniform 1000;      // heat flux / [W/m2]
            Ta              uniform 300.0;     // ambient temperature /[K]
            h               uniform 10.0;      // heat transfer coeff /[W/K/m2]
            thicknessLayers (0.1 0.2 0.3 0.4); // thickness of layer [m]
            kappaLayers     (1 2 3 4)          // thermal conductivity of
                                               // layer [W/m/K]
            value           uniform 300.0;     // initial temperature / [K]
            kappaName       none;
        }

but Incase if I want to input the heat flux as a heat generation rate in W/m³. What should I be doing? How can I add the heat generation source?. Looking forward to see some suggestions.
