The static aero-elastic computation with polyhedron grid was introduced. The CFD computational efficiency and deformation ability of polyhedron grid were studied based on M6 numerical example and interpolation method of radial basis function. The static aero-elastic numerical value was calculated with the use of AGARD 445. 6 wing. The results show that the polyhedron grid possesses the advantages of computational efficiency,deformation ability and accurate calculation results,so it is suitable to the static aero-elastic computation.
