【Abstract】 HT5\"SS]The relationship among number of elements, number of nodes, number of the edges on the boundary and number of close boundaries in the mesh drawing of finite element analysis is infered by a suitable variation of Euler equation. The arithmetic that can be used to judge whether there is duplicate of node numbers or lose of element numbers in the mesh drawing with it is also got. A simple method used to judge the integrity and the accuracy of a model is found.更多还原
