FLI animations

FLI software

ppm2fli
Producing FLI animation files.
The fliplay applet
Playing FLI animations using a JAVA applet.
pixmax
A simple 3d-plot utility. Many of the images in the FLI-animations below were generated using this program.

Examples Part I
To view the following animations a browser which supports JAVA applets is required, and the JAVA option has to be enabled. Some of the animations may require a lot of memory. This depends on the used browser and the system. A true-color graphic gives the best visual results, but requires more main memory. If one has a slow connection but a 4.x browser, the Examples Part II below may be a better starting point. There the FLI files are transferred in compressed form.

High speed train High speed train
320x240, 160 Kb, 103 frames, Povray animation

Monopole field Monopole field
320x240, 470 Kb, 25 frames, example with physical background

Dipole field Dipole field
320x240, 330 Kb, 25 frames, example with physical background

Pulse Pulse
320x240, 630 Kb, 76 frames, result of numerical simulation, propagation of a pressure pulse
(view with visible border of images used internally by fliplay)

Laval nozzle Laval nozzle
400x200, 660 Kb, 51 frames, result of numerical simulation, startup process in a Laval nozzle

Vortex-airfoil interaction Vortex-airfoil interaction
320x240, 580 Kb, 67 frames, result of numerical simulation, vortex passing an airfoil
(same but 134 frames, 720 Kb, no reverse, runs smoother)


Examples Part II
In the following examples the FLI-files are transferred in compressed form. Because the unzip is done using a Java class, which is not included in Java 1.0, some older browsers may not work.
