Journal ArticleDOI
Fully anisotropic 3-D EM modelling on a Lebedev grid with a multigrid pre-conditioner
TL;DR: In this paper, a finite-difference discretization of frequency-domain Maxwell's equations on a Lebedev grid is presented for 3D electromagnetic simulations in conducting media with general electric anisotropy.
Journal ArticleDOI
Fast multimodel finite-difference controlled-source electromagnetic simulations based on a Schur complement approach
TL;DR: In this paper, the Schur complement approach is applied to a frequency-domain finite-difference method for fast multimodel 3D electromagnetic simulations by applying a Schur complements approach to a direct solver and with constrained inversion algorithms in view.
Journal ArticleDOI
Large-scale 3D EM modeling with a Block Low-Rank multifrontal direct solver
Daniil V. Shantsev,Piyoosh Jaysaval,Sébastien de la Kethulle de Ryhove,Patrick R. Amestoy,Alfredo Buttari,Jean-Yves L'Excellent,Théo Mary +6 more
TL;DR: A study in a scenario where simulations are required at multiple source locations shows that the BLR solver can become competitive in comparison to iterative solvers as an engine for 3-D controlled-source electromagnetic Gauss–Newton inversion that requires forward modelling for a few thousand right-hand sides.
Journal ArticleDOI
Rigorous interpolation near tilted interfaces in 3-D finite-difference EM modelling
Daniil V. Shantsev,Frank A. Maaø +1 more
TL;DR: In this article, a rigorous method for interpolation of electric and magnetic fields close to an interface with a conductivity contrast is proposed, which can handle arbitrary orientation of interface with respect to the grid.
Journal ArticleDOI
Efficient 3-D controlled-source electromagnetic modelling using an exponential finite-difference method
TL;DR: In this paper, an efficient numerical scheme for 3D electromagnetic (EM) simulations using an exponential finite-difference (FD) method with non-uniform grids was developed.
