摘要/Abstract

摘要： 在大变形流体力学问题的数值模拟中,常常会涉及到计算网格的重分.基于不同网格的物理量传递便是所谓的重映技术.基于ENO插值的思想,发展了一类适用于任意网格的ENO守恒重映算法,并给出了数值结果.

关键词: 重映技术, 任意网格, ENO插值

Abstract: In the research of simulation for problems with large distortion in fluid dynamics, it is often required to re-construct the computational meshes. The technique transferring physical quantities between the two computatioal meshes is called as rezoning (remapping). Based on ENO interpolation idea, in this paper, a new kind of conservative ENO rezoning (remapping) algorithm is developed to structure and unstructured computational meshes. Finally, the numerical results show that the algorithm appears to be effective.

Key words: rezoning (remapping)technique, arbitrary meshes, ENO interpolation
