A Simple FEM for Multi-Scale Problem

Abstract:

For the problem∂⁄∂_xi(^∂ij(x/ε)∂^uε/∂_xi∂)=f(x), we present a multiscale FEεM to solve it when Ω is a complete periodic structure. The algorithm holds two characteristics: First the strain exists good accuracy on boundary layer; Second the computer memory that it needs is independent of ε .We use numerical experiments to investigate our results.
