Adaptive research on non-overlapping domain decomposition algorithm for concaveangel exterior problems

以各向异性方程为例,在非重叠型区域分解算法的基础上,研究了无界凹角区域上的自适应有限元算法,并且讨论了此算法离散问题迭代的收敛性,最后将它与均匀网格划分进行对比,并用数值例子证明自适应算法的可行性与有效性。

Based on the D-N alternating method for concave exterior problems,taking anisotropic exterior equation as an example,this paper studies the adaptive mesh methods and discusses the convergence.Finally,a numerical example comparing with adaptive meshing and uniform meshing is given to prove the feasibility and effectiveness of the adaptive mesh method.
