In multidisciplinary coupled calculations represented by aeroelastic calculations, structural deformation will lead to deformation of the fluid solution domain. It is necessary to develop a mesh deformation technology with good versa-tility, high computational efficiency and strong applicability to meet the calculation needs of aerodynamic forces. The dynamic mesh technology based on the radial basis function (RBF) interpolation method has strong deformation ability and is applicable to the deformation calculation of any type of mesh.
