ABSTRACT
The main contents of this paper’s design include infinitely perturbation interpolation method and RBF radial basis function dynamic grid method. The results of dynamic grid generation are compared. Observe which generation algorithm is more reasonable and the grid quality is higher[1]. With the development of computer equipment and computing technology, CFD is often used in various disciplines such as optimization design, aeroelasticity, thermal analysis, and pneumatic servo elasticity. For these problems, the linear method can be well solved under the conditions of small disturbance, but the nonlinear motion method is needed for the vibration induced eddy current, transonic flutter, and large control surface motion in complex flow field, and it needs to rely on large-scale Parallel computing platform technology[2]. The research results show that the infinite perturbation interpolation method is suitable for grid deformation with small perturbations. The generation efficiency is high and the algorithm is easy to implement. Radial Basis Function algorithm can maintain a higher mesh quality. The disadvantage is that the operation speed is slow and the algorithm is difficult to implement.
