### 10.4.1. Fluid Models

Information on radiation modeling in multiple domains is available in Domain Considerations.

#### 10.4.1.1. Include Boundary Temperature Slip

Optional parameter. For simulations where thermal radiation is by far the most dominant mode of heat transfer, a temperature slip must be allowed at physical boundaries (Siegel and Howell). By default, the temperature slip is not included.

Information on the mathematical implementation of this is available. For details, see Rosseland Model.

#### 10.4.1.2. Spectral Model

See Spectral Model.

#### 10.4.1.3. Scattering Model

See Scattering Model.
