Following on from "Transparency Reveals Hidden CFD Secrets," using symmetry is another way to reveal the hidden secrets of your Computational Fluid Dynamics (CFD) simulations.

CFD Simulation of Airflow Around a CarVelocity contours on symmetry plane

If you can build your flow volume to take advantage of symmetry, then not only will it reduce the simulation size and speed up your simulation turnaround time by a factor of two, but it will also let you reveal the hidden details on the center face of your simulation.

The symmetry plane face can support standard visualization approaches, such as contours and vectors.
