A reduce points algorithm of radial basis function dynamic mesh method

摘要

A reduce points algorithm was presented and applied to radial basis function dynamic mesh method. According to the given error, the algorithm had chosen some points form all the points on the CFD surface mesh. By interpolating an approximately surface on the selected points, the algorithm fill the drawback of radial basis function dynamic mesh method by reducing the computation time and storage. Taking m6 wing as an example, the simulation results show the initial point's insensitivity and the high efficiency of this algorithm. The algorithm can reduce the computation time of the dynamic mesh several times or even more. This property would be helpful in reducing the nonlinear aeroelasticity computation time and storage.
