摘要:
有限元网格图形的自动生成及细化是进行有限元计算的一个重要环节,它直接关系到运算的速度和准确性。该文采用“分形”理论建立了有限元网格图形自动生成中的细化递推模型,它不同于传统的网格自动生成中的“树”理论,而是采用了“分形”过程中的自相似性。它具有运算速度快,内存占用少的特点,尤其适用于有限元分析过程中的前处理。这种方法不仅适用于二维系统的有限元分析,同时也可推广到三维系统
Abstract:
T he automat ic generat ion of FEM mesh and it s refinement is the key in the FEM calculat ion. It direct ly ef fect s the calculat io n speed and accuracy . In this paper, an iterated model of r ef inement in the pro cessing of automat ic mesh generat ion of FEM is built . It is dif ferent f rom t radit ional “t ree”co ncept s in the automat ic generat ion o f meshs instead of using self-similar ity which appears in fractal processing. It is characterized by it s quick calculat io n and less memory . It is suited in part icular for the pr ocedure of pre pr ocessing in the FEM. T his appro ach not o nly f it s tw o dimensional system but thr ee dimensional sy stem as w ell. It pr ovides a new metho d for FEM sof tw ar e desig n.
