Analysis of nonconforming IFE methods and a new scheme for elliptic interface problems
ESAIM-MATHEMATICAL MODELLING AND NUMERICAL ANALYSIS, 57(4), 2041–2076.
author keywords: Interface problem; Nonconforming; Immersed finite element; Unfitted mesh
TL;DR:
This paper develops a new nonconforming IFE method with additional terms locally on interface edges which removes the limitation of the conventional partially penalized I FE method and derives the optimal approximation capabilities of both the Crouzeix-Raviart and the rotated-$Q_1 IFE spaces via a unified approach which can handle the case of variable coefficients easily.
