The "Preferences" window is a comprehensive tool for adjusting RealFlow to your special needs. These settings do not only influence RealFlow’s look and feel, they also have a very strong influence on simulation speed. You can control almost anything and tailor it to your personal taste or maximum performance. The window is classified into several panels according to their particular function. Though some of these setting have a global impact, they can also be changed individually for each scene, for example “FPS output” or the number of substeps. To open the "Preferences" window, please choose

Edit > Preferences... (Windows/Linux)

RealFlow > Preferences... (OS X)

The window consists of two parts. The left part is a menu tree with all available sections and you can open each one by simply clicking on it. The appropriate contents are then shown in the right section.
