Quadrilateral and Hexahedral Immersed Finite Element Methods for Elliptic Interface Problems

Fangfang Qin, Haifeng Ji

Immersed finite element (IFE) methods provide an effective framework for solving interface problems on unfitted meshes. The basic idea underlying IFE methods is to modify standard…

Accurate gradient computations at interfaces using finite element methods

Fangfang Qin, Zhaohui Wang, Zhijie Ma +1

New finite element methods are proposed for elliptic interface problems in one and two dimensions. The main motivation is not only to get an accurate solution but also an accurate…
