AUTOMATIC-GENERATION OF FINITE-DIFFERENCE MESHES BY AN EVOLUTIONARY ALGORITHM

This paper describes the use of an evolutionary algorithm for the gene ration of a graded finite difference grid, which makes a good as possi ble approximation of the input geometric objects, The algorithm is spe cialized to 2-dimensional polygonal structures, because the aim was to get a simulation model for Printed Circuit Board structures, The algo rithm itself and the quality function applied are explained and an exa mple of a PCB structure, which was discretized by the coded version of the algorithm, is shown.
