A direct finite element method for elliptic interface problems [PDF]
arXivIn this paper, a direct finite element method is proposed for solving interface problems on simple unfitted meshes. The fact that the two interface conditions form a $H^{\frac12}(\Gamma)\times H^{-\frac12}(\Gamma)$ pair leads to a simple and direct weak formulation with an integral term for the mutual interaction over the interface, and the well ...

Development of Steel Representation as Embedded Bars in Concrete Using Finite Element Method
Journal of Engineering and Sustainable Development, 2008 A new model for embedded bar formulation in the finite element analysis is presented, this new model differs from the conventional models, that it can represent the bar in a more accurate way, also it can deal with curved and/or complicated bar geometry.

Binary black hole simulation with an adaptive finite element method II: Application of local discontinuous Galerkin method to Einstein equations [PDF]
arXiv, 2018 Finite difference method and pseudo-spectral method have been widely used in the numerical relativity to solve the Einstein equations. As the third major category method to solve partial differential equations, finite element method is much less used in numerical relativity. In this paper we design a finite element algorithm to solve the evolution part

An Optimal and Robust Nonconforming Finite Element Method for the Strain Gradient Elasticity [PDF]
arXivAn optimal and robust low-order nonconforming finite element method is developed for the strain gradient elasticity (SGE) model in arbitrary dimension. An $H^2$-nonconforming quadratic vector-valued finite element in arbitrary dimension is constructed, which together with an $H^1$-nonconforming scalar finite element and the Nitsche's technique, is ...

A general quadratic enrichment of the Crouzeix--Raviart finite element [PDF]
arXivThe Crouzeix--Raviart finite element method is widely recognized in the field of finite element analysis due to its nonconforming nature. The main goal of this paper is to present a general strategy for enhancing the Crouzeix--Raviart finite element using quadratic polynomial functions and three additional general degrees of freedom.
