我们数值模拟海洋CSEM测量使用有限元方法。非结构化四面体网格很容易允许包含任意海底测深，以便以接近现实的方式将自然环境映射到模型中。一次/二次场方法以及自适应网格细化策略提高了解的精度。海底测深显示出显着的三维效果相比，一维，平坦的海底模型。
We numerically simulate marine CSEM measurements using the finite element method. Unstructured tetrahedral meshes easily allow for the inclusion of arbitrary seafloor bathymetry so that natural environments are mapped into the model in a close-to-reality way. A primary/secondary field approach as well as an adaptive mesh refinement strategy improve the solution accuracy. The seafloor bathymetry is shown to produce significant three-dimensional effects compared to a onedimensional, flat seafloor model.
