数值模拟两层有限大小地层中多电极电流场分布

摘要

This article is based on Principle of superposition method, studied by the COMSOL Multiphysics to build the two layers of ifnite-sized conductive medium modeling,and simulated the current ifeld distribution when the multi-electrodes exist simultaneously,then compared it to analytical solution, veriifed that using the ifnite-sized modeling to simulate the inifnite layers were reasonable.%文章根据叠加法原理，采用COMSOL多物理场有限元数值计算软件建立有限大小的两层导电媒质模型，并对多电极同时存在时电流的分布进行了仿真计算，并将之与解析解进行了比较，验证了用有限大小的模型来模拟无限大地层的合理性。
