One-step Monte Carlo global homogenization based on RMC code
Due to the limitation of the computers, the conventional homogenization method is based on many assumptions and approximations, and some tough problems such as energy spectrum and boundary condition are faced. To deal with those problems, the Monte Carlo

A priori error analysis for transient problems using Enhanced Velocity approach in the discrete-time setting [PDF]
Time discretization along with space discretization is important in the numerical simulation of subsurface flow applications for long run. In this paper, we derive theoretical convergence error estimates in discrete-time setting for transient problems ...

Sound transmission loss of particulate filter of exhaust system by homogenization method
Diesel or gasoline particulate filters are included in almost all vehicles to clean emission gas from internal combustion engines. On the other hand, a new regulation for vehicle noise emission has been into operation, and noise from exhaust system must ...

Homogenization of an interface highly oscillating between two concentric ellipses
The main purpose of this paper is to find the homogenized equation and the associate continuity conditions in the explicit form of a boundary-value problem in a two-dimensional domain with an interface oscillating rapidly between two concentric ellipses.

Asymptotic Preserving numerical schemes for multiscale parabolic problems [PDF]
We consider a class of multiscale parabolic problems with diffusion coefficients oscillating in space at a possibly small scale $\varepsilon$. Numerical homogenization methods are popular for such problems, because they capture efficiently the asymptotic

Numerical Methods for Multilattices [PDF]
Among the efficient numerical methods based on atomistic models, the quasicontinuum (QC) method has attracted growing interest in recent years. The QC method was first developed for crystalline materials with Bravais lattice and was later extended to ...
