Talk:Finite element updating

'Finite Element Updating is a process of making finite element models better reflect measured data. It has mainly been applied to structural analysis and damage detection in structures. There are two main approaches to finite element updating and these are direct methods which do not account for physical characteristics of structures and iterative models which are physically realistic. Since the process of matching a finite element model to measured data is essenttially an optimization method many methods such as particle swarm optimization, genetic algorithm and simulated annealing have been used.
