Algebraic multigrid preconditioning for finite-element methods for 3-D electromagnetic modelling in geophysics

Efficiency of a 3-D electromagnetic numerical modelling scheme is critical for its future use within a 3-D electromagnetic inversion algorithm. Therefore, we have developed and implemented a more elaborate preconditioning technique for Krylov subspace methods to improve the performance and reduce th...
