SuperComputing (SC’18): Computing Planetary Interior Normal Modes with a Highly Parallel Polynomial Filtering Eigensolver

Abstract: A highly parallel algorithm has been developed and exploited to compute the planetary normal modes of the elastic-gravitational system, which is approximated via the mixed finite element method on unstructured tetrahedral meshes. The eigenmodes of the relevant generalized eigenvalue problem were extracted by a Lanczos approach combined with polynomial filtering. In contrast with the standard […]
