CFD Online Discussion Forums

Hello guys!!!

I need a help. I am new to OpenFOAM as well as CFD. so kindly help me.
I need to apply time varying heat flux as boundary condition. I know that there is wallHeatFlux. I tried to use wallHeatFlux in T as follows:

Code:

 

patch76

    {

        type            wallHeatFlux;

        value           uniform 1;

    }

    patch78

    {

        type            wallHeatFlux;

        value           uniform 1;

    }

    patch80

    {

        type            wallHeatFlux;

        value           uniform 1;

    }

but i am getting the following error.

Code:

Reading thermophysical properties

    Trying to construct an genericFvPatchField on patch patch76 of field h



    From function genericFvPatchField<Type>::genericFvPatchField(const fvPatch& p, const DimensionedField<Type, volMesh>& iF)

    in file fields/fvPatchFields/basic/generic/genericFvPatchField.C at line 45.

I know this is for constant heat flux. it would be helpful if u can tell me how to include time varying heat flux. i couldnt find any useful resources online for that aspect.
