Optimized Solutions for Defect Characterization in 2-D Inverse Eddy Current Testing Problems Using Subregion Finite Element Method

A computational technique is presented in this paper which improves finite element method (FEM) in solving inverse problems. Subregion method is used to select and isolate the area of interest where design parameters for defect shape are updated. An elastic mesh generator is developed in this paper...
