So far we have only seen 2D flat CFD image results. These give an overall color coded velocity for that slice but few clues about what the actual airstream would look like passing through the model. Fortunately, the modeling software “Simulation” by Autodesk, allows you to run traces trough your model and they follow the air path and provide a better visual understanding of EXACTLY how air flows through the nose. All models have the same tracer set up, an array of 20×40 traces.
