QM/MM methods are a prototypical class of multiscale simulation schemes.They embed a quantum mechanical simulation of a "region of interest" in a bulk regio
In this talk we will present recent developments of multiscale methods for problems involving different physics at the microscopic and the macroscopic level
In this report,we develop a partially penalty immersed finite element method on triangular grids for an elliptic interface problem.On interface elements,the
We consider the approximation of elliptic eigenvalue problem with an immersed interface.The main aim of this paper is to prove the stability and convergence
Superconvergence and a posteriori error estimators of recovery type are analyzed for the 4-node hybrid stress quadrilateral finite element method proposed b
We present a simple method at material interface to remove numerical oscillations when the finite-difference time domain(FDTD)method is used to solve Maxwel
First we construct a conforming rectangular element and a conforming cubic element only with the degrees of freedom on an element 8+2 and 18+3 for stress an
We present a HDG method for linear elasticity on general polyhedral meshes,based on a strong symmetric stress formulation.The key feature of this method is
