Jukka Aho	5a07b3ab21	docs: Document Tutorial 3 API limitations, update test runner ... Current state discovery: - Element basis function evaluation broken (eval_basis! signature mismatch) - Field interpolation at integration points broken (same root cause) - Jacobian evaluation at integration points broken - These are fundamental API issues affecting multiple test paths Impact: - Tutorial 3 (basis functions) deferred until API fixed - Affects any code trying to evaluate fields at integration points - Related to Quad4 assembly issues discovered in Tutorial 4 Working tutorials (107/107 tests passing): - Tutorial 1: Element creation (5 tests) - Tutorial 2: Gmsh mesh reading (72 tests) - Tutorial 4: 1-element validation (35 tests) Next: Focus on tutorials using working APIs only	2025-11-09 02:58:09 +02:00
Jukka Aho	b91e81c125	test: Add Tutorial 2 - Gmsh mesh reading (72 tests passing) ... 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)	2025-11-09 02:24:06 +02:00
