AbstractHigh-quality FEA mesh generation is often a time intensive and costly process within the current iterative parametric product design cycle. A mesh optimization scheme is proposed and developed in which mesh creation parameters are optimized using an evolutionary algorithm. A mesh quality metric is proposed and used to study the effectiveness of the various mesh creation parameters and, in turn, to determine which should be used as design variables of the optimization problem. A genetic algorithm is employed to iteratively remesh 3-D surfaces and tend toward an optimal mesh based on the quality metric. The optimization approach was implemented on two components of Pratt & Whitney aircraft engine hardware. Results indicate that this approach is effective in generating high-quality meshes without altering the mesher itself, developing new meshing algorithms or post-processing meshes to improve element quality.
