Initial global, local and enriched global steps in a GFEM\(^\text {gl}\) analysis of a 3-D edge fracture—a disretizations for the initial global, local and enriched global problems—b initial global, local and enriched global solutions. This figure presents the global–local iterations between enriched global and local problems. The block arrows between problems represent exchange of information
