Class
Foam::greyDiffusiveViewFactorFixedValueFvPatchScalarField
Description
This boundary condition provides a grey-diffuse condition for radiative
heat flux, \c qr, for use with the view factor model
Usage
\table
Property | Description | Required | Default value
qro | external radiative heat flux | yes |
emissivityMode | emissivity mode: solidRadiation or lookup | yes |
\endtable
Example of the boundary condition specification:
\verbatim
<patchName>
{
type greyDiffusiveRadiationViewFactor;
qro uniform 0;
emissivityMode solidRadiation;
value uniform 0;
}
\endverbatim
