Description

The greyDiffusiveViewFactor is a boundary condition that provides a grey-diffuse condition for radiative heat flux, qr, for use with the view factor model.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            greyDiffusiveViewFactor;
    qro             <scalarField>;

    // Inherited entries
    ...
}

where:

Property Description Type Required Default
type Type name: greyDiffusiveViewFactor word yes -
qro External radiative heat flux scalarField yes -
