Step 3: Models

Models

1.   Enable the energy equation.

Models Energy Edit...

2.   Enable the DO radiation model.

Models Radiation Edit...

(a)   Select Discrete Ordinates (DO) in the Model list.

  The Radiation Model dialog box expands to show the related inputs.

(b)   Set the Flow Iterations per Radiation Iteration to 1.

  As radiation will be the dominant mode of heat transfer, it is beneficial to reduce the interval between calculations. For this small 2D case we will reduce it to 1.

(c)   Retain the default settings for Angular Discretization.

(d)   Click OK to close the Radiation Model dialog box.

  An Information dialog box will appear, informing that material properties have changed.

(e)   Click OK in the Information dialog box.
