摘要

摘要: 瞬变电磁正演是研究瞬变电磁响应规律的有效途径,瞬变电磁的高精度、快速三维正演技术,是当前瞬变电磁正演研究的热点。ANSYS软件中的Multiphysics模块也适用于瞬变电磁法的正演模拟问题。本文通过一些模型算例介绍了ANSYS软件在瞬变电磁场三维正演中的应用方法,包括建模、加载、求解设置、后处理的一般过程。数值计算结果表明,利用ANSYS软件进行瞬变电磁正演模拟具有很高的计算精度。合理使用ANSYS软件进行瞬变电磁响应模拟可以提高正演模拟计算的效率,为分析、理解瞬变电磁响应规律提供有力的支撑。

Abstract: The forward modeling is an effective way to study the characteristics of transient electromagnetic (TEM) responses. The high precision and fast 3D forward modeling technology is a hot spot in the study of TEM forward modeling. The multiphysics module in ANSYS software is suitable for the forward modeling of TEM. In this paper, the application method of ANSYS software in TEM 3D forward modeling is introduced by some model examples, including the preprocessing, loading, solution setting and post-processing. The numerical results show that the simulation of TEM forward modeling by using ANSYS software has high accuracy. The TEM forward modeling using ANSYS can improve the efficiency of forward simulation calculation and provide a strong support for analyzing and understanding the characteristics of TEM response.
