An algorithm for optimizing the node number of the numerical simulation of sheet metal forming processes is presented. The algorithm resequences the node according to the quotient obtained by dividing the summation of all node number by the number of elements next to the node. The algorithm enables us to minimize a matrix bandwidth, to reduce RAM, and to shorten computation time by optimizing fournodetetrahedron element of the numerical simulation of sheet metal forming processes.
