  We propose a Generalized Multiscale Finite-Element Method for elastic wave propagation in heterogeneous,anisotropic media,where we construct basis functions from multiple local problems for both the boundaries and interior of a coarse node support or coarse element.The application of multiscale basis functions can capture the fine scale medium property variations,and allows us to greatly reduce the degrees of freedom that are required to implement the modeling.
