摘要
本文提出求解场问题的另一种有限元一加权残差耦合法:分维耦合法,即在求解域的不同方向上,分别用有限元离散和加权残差求解;并采用统一的方式处理边界条件。结合三维温度场导出具体公式。本方法求解三维场问题可有效地减少计算量,与有限条法相比则具有更大的灵活性。
The Dimension-Dividing Coupling Method-a new coupling method of finie element and weighted residual for solving fidld problems is presented in this poaper, in which the finite element method and the weighted restidual method are used in different directions of the field and the boundary conditions are dealed with by mean of a unified way. As an ex ample, the general formulae for solving 3 - dimensional temoperature field problems is dirived. with this method. the amount of computation can be reduced efficiently. More over, compared with the finite stripe method, this method is more flexible.
