Radial basis function based mesh deformation applied to simulation of flow around flapping wings

► Mesh deformation based on radial basis functions is applied to flapping wings. ► RBF Mesh deformation results in high mesh quality at large amplitude motion. ► Thin plate spline RBF is applied to mesh deformation around a 3D flapping wing. ► The efficiency of the RBF mesh deformation is improved by coarsening and smoothing. ► RBF mesh deformation results in high mesh quality for 3D flapping wings.
