摘要
网格的生成是平面有限元计算的前提和基础,但当边界不规则时容易生成劣质单元,对计算造成影响.对比目前较为成熟的四边形网格生成方法,开发出以Visual Basic语言为基础的结构化有限元网格划分程序,生成较为规则的四边形单元.它具有操作简便,网格密度、单元数量可控制,生成的数据简单实用等特点,特别适用于小型结构的有限元分析.
The generation of grid is the precondition and foundation of plane finite element calculation,but poor units will be generated when there are irregular boundaries,which will affects the calculation results.Referring matured quadrilateral grid generation methods,a Visual basic program based on structured finite element grid portioning is developed,which will generate regular quadrilateral grid.It has the characteristics such as: easy to use,grid density and united quantity could be controlled,the data generated are brief and practicable,especially for finite element analysis of small structures.
