AI总结:

针对单相求积域自由边界问题,提出两种数值格式:快速迭代求解器(适应拓扑变化)和基于形状重建的拟牛顿法,数值实验验证了有效性。

摘要:

本文针对称为单相求积域的自由边界问题,提出了两种数值格式。第一种方法通过应用给定自由边界问题的性质,推导出一种快速迭代求解器。迭代过程经过调整,以适应拓扑变化的情况。第二种方法基于形状重建,建立了一种高效的形状-拟牛顿法。各种数值实验证实了所推导数值方法的效率。

英文摘要:

In this work, we present two numerical schemes for a free boundary problem called one phase quadrature domain. In the first method by applying the proprieties of given free boundary problem, we derive a method that leads to a fast iterative solver. The iteration procedure is adapted in order to work in the case when topology changes. The second method is based on shape reconstruction to establish an efficient Shape-Quasi-Newton-Method. Various numerical experiments confirm the efficiency of the derived numerical methods.
