AbstractA fast dynamic mesh method based on radial basis function (RBF) is developed, which can be suitable of the mesh deformation of any kind of topology. In order to improve the deforming efficiency, firstly, a searching algorithm coupling with a reduced surface point option is used for the choice of control points; then the RBF can be determined by the coordinates and deforming displacements of these control points; then, the deformations of volume mesh are calculated by point-to-point; lastly, the new mesh can be obtained by adding the deformations to the original mesh. To validate the deforming capability, several two- and three-dimensional meshes with rigid rotation are performed. Then, the method is used for the aeroelasticanalysis of the AGARD 445.6 standard model.
