What is GMsFEM for Elastic Wave Propagation about?

This document proposes a Generalized Multiscale Finite-Element Method (GMsFEM) to model elastic wave propagation in heterogeneous, anisotropic media. GMsFEM constructs basis functions from local problems to capture fine-scale variations and greatly reduce the computational cost compared to conventional finite-element methods. The document formulates both continuous and discontinuous Galerkin formulations of GMsFEM and applies it to three heterogeneous models, showing it can effectively model wave propagatio
