Articles published in the F#.NET Journal often culminate in fun graphical programs. Consequently, we have begun the process of uploading demos that everyone can download and enjoy. The first such demo, from the article Real-time Finite Element Materials simulation (15th June 2008), is now freely available for download from the F#.NET Journal web page.
This demo simulates a simple 2D material using finite element methods and the flexible object can be grabbed and pulled with the mouse in order to deform and even smash it:
The entire self-contained F# program is under 200 lines of code and uses Windows Presentation Foundation for easy and efficient real-time visualization.
