Hi,

I can't understand what's the difference using compressible:turbulentTemperatureCoupledBaffleMixe d or compressible:temperatureCoupledBase.

Main differece I can see is that compressible:turbulentTemperatureCoupledBaffleMixe d could be use for baffles and to specify layers, what else?

In any case considering the usage from the code

   {
        type            compressible::turbulentTemperatureCoupledBaffleMixed;
        Tnbr            T;
        thicknessLayers (0.1 0.2 0.3 0.4);
        kappaLayers     (1 2 3 4);
        kappaMethod     lookup;
        kappa           kappa;
        value           uniform 300;
    }

I can't understand what the keyword "value" means and what it is used for Can someone help?

Thanks

temperatureCoupledBase is designed to be a base (even the name implies so) class to derive other classes from. It is not intended to be specified as a type of a boundary condition imposed on a patch. temperatureCoupledBase provides some functionality to be reused by derived classes.

turbulentTemperatureCoupledBaffleMixedFvPatchScala rField is derived from temperatureCoupledBase and can be specified as a boundary condition.

value is an initial value explicitly assigned to every patch face for the first iteration. You can omit it letting the code calculate it based on other parameters specified.

Hi, sorry to disturb you. I coupled chtMultiRegionFoam with the modified interCondensatingEvaporatingFoam, the solver compiles without problems (just judging from the compiled results), but once the temperature solves, there will be an error. I put up my TEqn.H and 0/T, please help me see where the problem is.
