In the second chapter, we present an additive Schwarz preconditioner for the rotated Q_1 finite element discretization of second order elliptic problem.
我们在第二章中构造了求解用旋转Q_1有限元离散椭圆型偏微分方程的区域分解方法。
The second order elliptic problem is studied by using conforming finite element and nonconforming finite element in the different parts of the area respectively.
在区域的两个不同部分分别采用协调元和非协调元来研究二阶椭圆问题。
