Abstract
Paper presents problem of optimization of mesh selection for the most effective eddy current tomography forward transformation. Methods of forward tomography transformation based on Finite Element Method (FEM) have been previously reported. They are based on a calculation for all measurements points, to ensure proper results reconstruction. Proceeding calculation of forward transformation with FEM – based method requires a lot of computational power and a significant amount of time. In paper an idea for characteristic point selection is presented. Simulation time can be limited, by selecting proper measurement points and interpolating the calculation results. Paper presents two methods of point selection. One is based on a hybrid genetic algorithm and the second one is discretely linear with randomly generated initial state. Furthermore a comparison of computation time of utilized algorithms is presented, as well as the calculation results. Presented results confirm possibility of effective results interpolation for more efficient calculations in forward eddy current transformation.
