FloEFD, Mentor Graphics' general-purpose CFD software, tackles the difficult, time-consuming aspects of preparing a headlamp model for analysis. The first benefit is that the users can work directly on the native CAD model in their own CAD tool. This eliminates the step of transferring a neutral file format model to the analysis tool, followed by the typical need to clean up any translation errors due to this process. Next, the benefit of the immersed-boundary style of meshing used by FloEFD also impacts the geometry preparation. Because of this mesher the laborious step of simplifying and de-featuring the model can be greatly reduced.
The following example highlights FloEFD's capabilities in simulating headlights, with a particular focus on surface condensation modeling. Figure below displays the model and the relevant parts that were included in the simulation.
