 "Introduction to the spectral-infinite-element method"
   ~ by Hom Nath Gharti and Jeroen Tromp, Princeton University

   The governing equations for the elastic-gravitational deformation of
   an Earth model involve a perturbed gravitational potential. The
   gravitational potential is governed by Poisson’s equation inside
   the Earth and by Laplace’s equation in the rest of space. The
   infinite domain and large-scale nature of the problem poses
   difficult challenges for numerical simulations in 3D Earth models.
   In order to tackle these challenges, we introduce a
   spectral-infinite-element method by combining the spectral-element
   method with the mapped infinite-element method. Spectral elements
   are used to represent internal fields, and infinite elements
   represent the external gravitational field. Infinite elements
   naturally couple with spectral elements, thereby avoiding an
   iterative procedure which is necessary if the Poisson/Laplace
   equation has to be solved independently. Potential applications of
   new method include long-period seismic wave propagation, as well as
   quasistatic problems, such as post-earthquake relaxation and glacial
   isostatic adjustment.
