See [BNP98A] for a description of these crystalline evolution examples.

ODE type solver

A first set of simulations where obtained by using the crystalline evolution law first given by J. Taylor, under the assumption that faces do non break. Of course such evolution can be adapted even in case of breaking if the breaking lines are known in advance.

Reaction diffusion approximation

A second set of simulations where obtained (oct 1998- ) by using the Allen-Cahn type approach described in [Pao95] in 3D. The code is written in Fortran90 by F. Pasquarelli. The space discretization is obtained by a structured tetraedral grid of a cubic domain large enough to contain the initial surface. Graphics obtained by postprocessing output data with Geomview and Povray.
