MarshakRadiation

Description

The MarshakRadiation is a mixed boundary condition that provides a Marshak condition for the incident radiation field (usually written as G).

The radiation temperature is retrieved from the mesh database, using a user specified temperature field name.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            MarshakRadiation;

    // Optional entries
    T               <word>;

    // Inherited entries

}
