Mixed virtual volume methods for elliptic problems
Gwanghyun Jo, Do Y. Kwak
We develop a class of mixed virtual volume methods for elliptic problems on polygonal/polyhedral grids. Unlike the mixed virtual element methods introduced in \cite{brezzi2014basic…

Locally conservative immersed finite element method for elliptic interface problems
Gwanghyun Jo, Do Young Kwak, Young Ju Lee
In this paper, we introduce the locally conservative enriched immersed finite element method (EIFEM) to tackle the elliptic problem with interface. The immersed finite element is u…
