new program called Ellipsis. Having lagrangian integration points meant that the scientist using the code could track history and material properties through time. This allowed complex rheologies and geometries to be modelled easily and flexibly. Though Ellipsis only worked in 2D and in serial, it was extremely popular in the geophysics community. Currently Moresi, in partnership with the Victorian Partnership for Advanced Computing, is working on a parallel 3D version of Ellipsis called Underworld.
