The Physics of Microdroplets - Movies
This page contains links to some interactive 3D animations made from Surface Evolver
datafiles for the book The Physics of Microdroplets.
The movies illustrate the gradient-descent evolution algorithm used by the Evolver,
and are not designed to model actual physics. The Evolver does not do turbulence,
viscosity, inertia, and other bulk fluid physics. The motions shown are suggestive
of physical motion, at best.
These animations were made with HTML5 and WebGL, so they need a modern browser, namely
Firefox, Chrome, or Internet Explorer 11.

- Fig. 4-7 Drop moving uphill to hydrophilic region.
- Fig. 4-9 Drop sliding downhill due to gravity.
- Fig. 4-10 Drop climbing a step.
- Fig. 4-17 Drop sliding around a defect.
- Fig. 5-6 Stretched drop between planes moving to narrower end.
- Fig. 5-7 Flattened drop between planes moving to wider end.
- Fig. 6-21 Liquid plug oozing between pillars (the cover illustration).
