报告摘要: We consider higher-order unfitted finite element methods on Cartesian meshes with hanging nodes for elliptic interface problems, which release the work of body-fitted mesh generation and allow us to design adaptive finite element methods for solving curved geometric singularities. We will review the results for two-dimensional problems and introduce a new high order unfitted finite element method in three-dimension that improves the numerical stability of high-order unfitted finite element methods on arbitrarily shaped smooth domains. This talk is based on joint works with Ke Li, Yong Liu, Maohui Liu and Xueshuang Xiang.
