查询词典 mesh

Meshless method is a new numerical method on problem for determining solution of partial differential equation. It is an approximation method based on nodes, and doesn't need a mesh entirely or partly. Then the discontinuous problems, the extremely large deformations problems, and movable boundary problems, etc, can be solved by use to meshless without the re-meshing techniques. And not only the calculated precision can be guaranteed, but also the calculated difficulty can be decreased.

该方法主要是从整个传动过程中动态地考虑摆线轮与针齿齿面的受力情况，依据摆线轮与针齿的实际最先接触点的分布区间不同，对不同的等距与移距组合修形方式分别给出了动态受力分析方法，并且在整个传动过程中进行了优化搜寻，从而得出了整个传动过程中的接触力动态变化规律，相对以前的受力分析方法，计算的精度和准确性得到了提高。

The method involves an iterative procedure, which incrementally flattens a 3D triangular mesh by region growing and obtains a parameterization with free boundary. The result is then converted to a parameterization with regular boundary by conformal mapping. Our method accounts for both the angle and area distortion during parameterization, it yields a parameterization with less global distortion and no triangular flipping.
