Meshes used for the GFEM\(^\text {gl}\) analysis of a 3-D edge crack—a TET4/TET10 initial global mesh—b HEX20 initial global mesh—c local mesh—d TET4 enriched global mesh—e TET10 enriched global mesh—f HEX20 enriched global mesh. The analysis is performed with the HNA Abaqus-ISET solver and with ISET only for verification purposes. The same local discretization is used regardless of the element type adopted in the global problem
