Initial global and local problem used in the GFEM\(^\text {gl}\) analysis of a surface crack—a initial global problem with subdomain \(\Omega ^L\) shown—b local problem with boundary conditions on \(\partial \Omega ^L\backslash (\partial \Omega ^L \cap \partial \Omega )\). a shows that the initial global step does not model the surface crack. b Shows that the crack is introduced in the local step
