Ellipsis3D

Ellipsis3d is a three-dimensional version of the particle-in-cell finite element code Ellipsis, a solid modeling code for visco-elastoplastic materials. The particle-in-cell method combines the strengths of the Lagrangian and Eulerian formulations of mechanics while bypassing their limitations.

Ellipsis3d originated from CIItcom (CitCom version II), a multigrid mantle convection code developed by Louis Moresi. Subsequently, Chris Wijns contributed user-functionality and miscellaneous back end improvements. Later extensions to include the Cosserat continuum theory were introduced by Frederic Dufour. The two-dimensional version of ellipsis was extended into three dimensions by Richard Albert and Craig O'Neill.
