Viscoelastic full-waveform inversion is recognized as a challenging task for current acquisition deployment at the crustal scale. We have developed an efficient formulation based on a time-domain spectral-element method on a flexible Cartesian-based mesh.

Spectral Element Methods on Simplicial Meshes
2013We present a review in the construction of accurate and efficient multivariate polynomial approximations on elementary domains that are not Cartesian products of intervals, such as triangles and tetrahedra. After the generalities for high-order nodal interpolation of a function over an interval, we introduce collapsed coordinates and warped tensor ...

Overlapping Schwarz Methods for Unstructured Spectral Elements
Journal of Computational Physics, 2000The authors introduce and study a parallel and scalable domain decomposition method for unstructured and hybrid spectral element discretizations of elliptic problems. The spectral elements are affine images of the reference triangle or square in two dimensions and of the reference tetrahedron, pyramid, prism, or cube in three dimensions.

Parallel magnetotelluric modeling with Spectral Element Method
2021 International Applied Computational Electromagnetics Society (ACES-China) Symposium, 2021Improving the accuracy and speed of forward performance is of great significance to the effective application of numerical simulation. This paper studies the magnetotelluric forward based on spectral element method (Spectral Element Method, SEM). The second order partial differential equation satisfied by electromagnetic field is used as governing ...

Mimetic spectral element methods
AIP Conference Proceedings, 2015Mimetic spectral element methods are arbitrary order methods which aim to mimic the underlying physical structure of a PDE. This is best accomplished in terms of differential geometry in which the physical variables are considered as differential k-forms. At the discrete level, the system is represented by k-cochains from algebraic topology.
