Simplify your Geometry

Whenever possible simplify (or defeature) your geometry to represent the key elements of your design. Trying to configure a CFD simulation for a detailed CAD geometry can be a difficult task. For more background see "Design for Simulation then Manufacture".

Model Accuracy

To preserve model accuracy construct your key geometry elements (e.g., car, wheels, airfoils) at the global origin.
