The integral equation method (IEM) and differential methods have been widely applied to provide numerical solutions of the electromagnetic (EM) fields caused by inhomogeneity for controlled-source EM method. IEM has a bounded computational domain well-known its efficiency, whereas are commonly used complex geologic models. To use advantages two types approaches, hybrid is developed based on combination edge-based finite-element (vector FEM). In scheme, Maxwell’s equations secondary electric...
The streaming potential in porous media is one of the main constituents self-potential. It has attracted special attention environmental and engineering geophysics. Forward modeling potentials could be foundation corresponding data inversion interpretation, improving application effect self-potential method. traditional finite element method a large subdivision area computational quantity, artificial boundary condition not suitable for complex models. Helmholtz-Smoluchowski equation...
The controlled-source electromagnetic (CSEM) forward modeling with vector and scalar potentials could provide insights into the inductive galvanic effects. We have developed a finite-element (FE) algorithm for CSEM potentials. first-order nodal shape functions are used potentials, respectively. To mitigate null space thus nonuniqueness of caused by curl operator, we introduce new preconditioner constructed from an incomplete Cholesky decomposition zero fill-ins Laplacian approximation to...
