Two Data Transfer Functions with High Accuracy and Efficiency for Aeroelasiticity Simulation

Following the requirements of data transfer between the fluid-structure girds in aeroelasticity,a method based on radial basis function is introduced.A principle about how to chose compact support radius and a coupling program is proposed.Taking M6 wing as a example,we compare different functions in accuracy and efficiency.It is turn out that volume spline function and compact radial function C2 show good performance in accuracy and efficiency.These two fluid-structure interaction functions are suitable for engineering application.
