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