An Automated Finite Element Mesh Generation and Element Coding in 2-D Electromagnetic Inversion

摘要

An automated mesh generation and element coding in finite element modelling is developed for the optimisation of geometrical and physical model parameters of the 2-D structures. The approach is based on an automatic reconstruction of the mesh and the element codes for varying geometrical and physical parameters of the subsurface during the optimisation process. The efficacy of the approach is demonstrated through its application in forward modelling and inversion of the VLF electromagnetic data from the simple and complex subsurface structures.
