Mesh Modification Strategy for Aerodynamic Design through Evolution

In this work a mesh deformation strategy for an aerodynamic simulator used in an automatic design environment is presented. This strategy allows creating different alternatives within an evolutionary design process by following a low computational cost procedure. The mesh used to evaluate de fitness of each alternative in a computational fluid dynamic (CFD) solver doesn´t need to bet created for each design. The mesh is obtained as a modification of the boundaries of the mesh used in the previous evolution step minimizing the computational cost.
