Educational tutorial covering complete Gmsh.jl workflow: - Mesh generation recipe (2×5 structured Quad4 grid) - Reading nodes and extracting coordinates - Reading elements and topology - Physical group extraction for boundary conditions - Creating JuliaFEM Element objects from Gmsh data - Geometry field validation Features: - Co-located .msh file (10 elements, 18 nodes) for self-contained testing - Recipe script shows exactly how mesh was generated (reproducible) - Comprehensive tests (72 assertions) validating entire workflow - Runtime: ~3 seconds - Type-safe conversions (UInt64 → Int64 for connectivity) Tutorial series now: 77/77 tests passing (Tutorial 1: 5, Tutorial 2: 72)
