Structured Grid Generation Using the Artificial NeuralNetworks

摘要

Methods of using artificial neural networks (ANNs)rnto generation of the structured grids are analyzed inrnthis article. A general formulation of the ANNs in thernform of generalized mapping functions is presentedrnand then three different methods for using the ANNsrnfor the grid generation are suggested. The methodsrnare applied on some practical grid generationrnproblems and the strong and weakness of eachrnmethod is illustrated. The results show the goodrnapplicability and some advantages in comparison tornother usual grid generation methods for practical gridrngeneration problems.
