| Summary: | Mesh deformation method which independent of mesh topology and doesn’t need any grid-connectivity information is developed which based on the radial basis function interpolations. The method is computed by solving matrix problem which the size depends on the number of control points used in order to deform the mesh. The size is relatively small compared to actual size of mesh itself. The deformed mesh quality differs significantly with the quality of original mesh when applied with large deformation caused by translation or rotation. But for small deformation, the mesh quality isn’t changed significantly compared with the quality of original mesh. Type of radial basis function used is Gaussian RBF since it gives the best average mesh quality compared to other type of RBF. This mesh deformation method later implemented in optimization of airfoil NACA0012, RAE2822 and ONERA M6 wing in transonic flow to test implementing it to real case optimization. The optimization process goes properly and gives satisfactory results. |
