Abstract: In order to ensure conservative precision and monotonicity of a remapping algorithm and discontinuity with high resolution, a new kind of conservative RBF remapping algorithm is developed based on radial based function interpolation. Conservative precision is tested with a conservative error remapping algorithm. Numerical results are obtained for smooth and discontinuous functions. Compared with other remapping methods,the method gives good numerical results.

Key words: conservative remapping, reconstruction grids, radial based function
