In Xu et al. (Comput Struct 87:1416�1426, 2009) a novel Green-function-based multiscale stochastic finite element method (MSFEM) was proposed to model boundary value problems involving random heterogeneous materials. In this paper, we describe in detail computational aspects of the MSFEM explicitly across macro�meso�micro scales. Different numerical algorithms are introduced and compared in terms of numerical accuracy and convergence.
