These examples are simple problems designed to demonstrate the thermal radiation analysis process. The first example, steady-state radiative boundary conditions, is a two-enclosure radiative model. The second, parallel semi-infinite plates, is an idealized situation for which the correct thermal solution is known. The third example, more representative of a real world problem, models the interior of a reaction chamber.

In the first example, a step-by-step model definition is given, including figures showing the Patran forms. For the subsequent examples, to avoid repeating the forms, only the significant model data is given.
