研究了齐次问题的级联共轭梯度(CCG)方法与非重叠域分解(DD)方法的组合。应用界面上的砂浆有限元以允许相邻子域中的网格不匹配。对于材料跳跃问题,该方法被设计为级联方法的替代方案。
A combination of the cascadic conjugate gradient (CCG) method for homogeneous problems with a non-overlapping domain decomposition (DD) method is studied. Mortar finite elements on interfaces are applied to permit non-matching grids in neighboring subdomains. For material jump problems, the method is designed as an alternative to the cascadic methods.
