The study develops the displacement error recovery method in a mesh free environment for finite element solution employing radial point interpolation (RPI) technique. RPI technique uses basis functions (RBF), along with polynomials to interpolate fields node patch and recovers field. global local errors are quantified both energy L2 norms from post-processed considers multi-quadrics/gaussian/th...

In this paper, we propose a new multilevel univariate approximation method with high order accuracy using radial basis function interpolation and cubic B-spline quasi-interpolation. The proposed approach includes two schemes, which are based on radial basis function interpolation with less center points, and cubic B-spline quasi-interpolation operator. Error analysis shows that our method produ...
