在过去的十年中，在广泛的地电磁数值模拟应用领域取得了巨大的进展。由于工业需求的增加，这一趋势得到了支持，主要是由油气和矿石勘探行业引起的。另一方面，数据采集技术的可靠性和准确性的提高进一步推动了这一发展。本文将重点介绍地电磁学数值模拟的进展和面临的挑战。本文综述了三维感应问题的时域和频域离散解的最新进展。特别地，求解偏微分方程的常用数值技术如有限差分法和有限元法的优缺点将被考虑。
During the last decade, tremendous advances have been observed in the broad field of numerical modelling for geo-electromagnetic applications. This trend received support due to increasing industrial needs, mainly caused by hydrocarbon and ore exploration industry. On the other hand, the increasing reliability and accuracy of data acquisition techniques further spurs this development. In this review, we will focus on advances and challenges in numerical modelling in geo-electromagnetics. We review recent developments in the discrete solution of the 3-D induction problem in the time and frequency domains. Particularly, advantages and disadvantages of the common numerical techniques for solving partial differential equations such as the Finite Difference and Finite Element methods will be considered.
