为保证重映过程的高守恒精度和单调性,并且在间断处具有极高的分辨率,基于径向基函数(RBF)插值法构造了一类适用于任意网格的RBF守恒重映算法,通过计算守恒误差测试重映算法的守恒精度。将该方法用于光滑函数和含有间断的函数,并与其它守恒重映方法比较,表明该方法数值结果较好。
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.
