摘要 提出一种在采用高阶基函数时将定义在大尺寸单元上的高阶基函数与定义在小单元上的低阶基函数混合使用的方法.该方法可以合理的使用基函数的阶数与个数,得到准确的计算结果,并且较大幅度地提高了计算效率.该方法适用于对复杂结构目标进行精确建模,并同时具有高阶基函数与低阶基函数的优点. A new method is introduced to model the complex structure object by using the higher order bases on the large patches and the low order bases on the small patches in this paper. This method will utilize the order of the different bases and the number of unknowns reasonably.Furthermore, tiffs method will get the accurate results but not increase the burden in solution and keep the merit of the two kinds of bases.
