Despite the fact that computational fluid dynamics (CFD) software is now
(relatively) fast and freely available, it is still amazingly difficult to use.
Inaccessible software imposes a significant entry barrier on students and
junior engineers, and even senior researchers spend less time developing
insights and more time on software issues. Lily Pad was developed as an initial
attempt to address some of these problems. The goal of Lily Pad is to lower the
barrier to CFD by adopting simple high-speed methods, utilising modern
programming features and environments, and giving immediate visual feed-back to
the user. The resulting software focuses on the fluid dynamics instead of the
computation, making it useful for both education and research. LilyPad is open
source and available online at https://github.com/weymouth/lily-pad for all use
