Radiation missing in buoyantBoussinesqSimpleFoam

Hi everyone,

before reporting it as a bug I wanted to check whether I'm missing anything here.
In the buoyantBoussinesqPimpleFoam solver the TEqn states the following:

Code:

    fvScalarMatrix TEqn

    (

        fvm::ddt(T)

      + fvm::div(phi, T)

      - fvm::laplacian(alphaEff, T)

     ==

        radiation->ST(rhoCpRef, T)

      + fvOptions(T)

    );

However, in the respective file in the buoyantBoussinesqSimpleFoam solver the part

Code:

radiation->ST(rhoCoRef, T)

is missing:

Code:

    fvScalarMatrix TEqn

    (

        fvm::div(phi, T)

      - fvm::laplacian(alphaEff, T)

     ==

        fvOptions(T)

    );

Also in the buoyantSimpleFoam and buoyantPimpleFoam this line is included. Obviously the steady-state Boussinesq solver cannot be used with radiation. Is there any reason or has it just been forgotten?

dear hanness

do you have any update on this issue?

Hi all,

as it looks like in the solver is no radiation term included.
This is not a bug or a missing thing. Its only the fact that this solver is not build with radiation. In the official user guide there is no information about radiation.

If you want to have the SIMPLE algorithm to have an option for radiation you should implement it - recompile it - or build a new solver and then everything is fine.
