Auto mesh algorithm of the finite cover system in the numerical manifold method 数值流形方法物理覆盖系统的自动剖分
A criterion theorem of having no finite coverings for a finitely generated module m over a semisimple ring r is given 对半单环上有限生成左模给出一个无有限覆盖的判定定理。
For complicated object with arbitrary shape , the finite cover system of 3d nmm and mesh can be automatically generated by program through using these classes and trees 对任意形状的复杂结构体,用流形方法的数据类实现了流形单元有限覆盖系统的全自动生成及网格自动划分。
Manifold , as the main theme of differential geometry and analysissitus , has a basic structure composed of finite cover system and contact functions between covers , which could be overlapped or even folded 与通常的网格不同,覆盖可重叠或折叠产生一个组合空间,因此流形方法是追求一切空间上的所有解法。
