Numerical simulations

The simulations herein were computed using a numerical scheme presented in several papers of mine:  about the general scheme,  about the surface diffusion flow,  about the Willmore flow in the radially symmetric case.

The dynamic pages use JavaScript1.2, and work best with Firefox version 3 or higher, Netscape Communicator/Navigator version 4 or higher, or Microsoft Internet Explorer version 4 or higher, or Opera version 5 or higher. Playing of the animations does not work with Netscape Communicator/Navigator version 3.x, but at least the single-stepping works with those browsers.
