Surface Evolver 2.70

Work with a set of tools for liquid surface generation and simulation for personal computers. Check out the options for simulating the combination and interaction of various forces and constraints forming the surface type represented by a union of triangle shapes.

Surface Evolver is an interactive program for the modelling of liquid surfaces shaped by various forces and constraints. A surface is implemented as a simplicial complex, that is, a union of triangles. The user defines an initial surface in a datafile. The Evolver evolves the surface toward minimal energy by a gradient descent method. The aim can be to find a minimal energy surface, or to model the process of evolution by mean curvature for surface tension energy in the context of varifolds and geometric measure theory.
