Aerodynamic design optimization using knowledge extraction from analyzing unstructured surface meshes

摘要

A computer-assisted method for analysing data representing the optimization of real-world designs according to at least one criterion, expressed in physical entities, wherein - by an iterative optimization algorithm modifications of the design are computed, - the design data are represented by unstructured triangular surface meshes, - a displacement measure representing the geometrical differences between at least design modifications is calculated, - the performance differences, expressed by the at least one physical criterion, between said at least two design modifications is calculated, and - a sensitivity information signal is output representing the interrelation between the displacement measure and the performance differences.
