 values, and saves them into a raw data file that can then be converted into a movie file with tools such as ffmpeg. The
 rendering is simplified compared to :ref:`simulate.cc <saSimulate>` because there is no user interaction, visualization
 options or timing; instead we simply render with the default settings as fast as possible. The dimensions and number of
