Multiscale finite element for problems with highly oscillatory coefficients
The authors study a multiscale finite element method for solving a class of elliptic problems with finite number of well separated scales. The method is designed to efficiently capture the large scale behavior of the solution without resolving all small scale features. This is accomplished by constructing the multiscale finite base functions that are adaptive to the local property of the differential operator. The construction of the base functions is fully decoupled from element to element, thus the method is perfectly parallel and is naturally adapted to massively parallel computers. Main results: The authors present the convergence analysis of the method along with the results of given numerical experiments. Moreover, some generalization of the multiscale finite element method are proposed.
