Numerical solution of the forward magnetic field problem for models with irregular polyhedron discretization taking into account the "demagnetization effect"

A performance-effective numerical method for magnetic field calculation is proposed. The method works with irregular polyhedron discretization which enables us to construct models with magnetic objects of arbitrary shape. As a case study, a model of a well in plane-parallel layer is considered. The model is approximated with dense irregular grid, elements of which are polyhedrons. With the help of conjugate gradient method, we solve "demagnetization effect" equation and calculate total magnetic field on the plane above the well. For a well of 0.25m radius and 8m height "demagnetization effect" is of order of 2% relative to the field induced by the object placed in equivalent of Earth magnetic field. © 2020 American Institute of Physics Inc..

Study of the anomalous magnetic field structure in the Ural region using parallel algorithms

The anomalous structure in the magnetic field of the Ural Region has been studied in the segment bounded by 52°-64° N and 54°-66° E. Analytical apparatus for upward continuation of airborne magnetic data to different heights was applied. To recalculate magnetic field, parallel algorithms and software for multiprocessor computers were used. Maps of magnetic anomalies for different ranges of wave lengths showing the distribution of magnetization in the layers of the Earth's crust were built. © 2012 Pleiades Publishing, Ltd
