| 摘 要： | 在大变形流体力学问题的数值模拟中,任何方法都必须考虑网格重分或网格自适应,只要改动网格就涉及重分,或自适应后从旧的、扭曲的网格到新网格的守恒量重映,包括质量、动量和能量.在研究样条函数逼近的基础上,给出一种物理量重映的对结构网格和非结构网格均适应的算法,并给出了数值结果.

| Abstract: | The method in computational fluid dynamics requires the periodic remapping of conservation quantities such as mass, momentum, and energy from old or distorted meshes to some other arbitrarily defined meshes. This is a type of interpolation procedure, which is usually constrained to be conservative and monotone. A type of remapping algorithms using spline-approximating methods are presented for numerical simulation codes applied to unstructured or adaptive meshes. |
