Introduction

This tutorial illustrates the set up and solution of flow and thermal modelling of a headlamp. The discrete ordinates (DO) radiation model will be used to model the radiation.

This tutorial demonstrates how to do the following:

• Read an existing mesh file into ANSYS FLUENT.

• Set up the DO radiation model.

• Set up material properties and boundary conditions.

• Solve for the energy and flow equations.

• Initialize and obtain a solution.

• Postprocess the resulting data.

• Understand the effect of pixels and divisions on temperature predictions and solver speed.
