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
- Added 118 lines of heat transfer code to src/problems_heat.jl
- Problem types: Heat (3D), PlaneHeat (2D)
- Fields: thermal conductivity, heat source, heat flux, convection
- Fixed Element type signatures (Element{M,B})
- NOTE: Tests currently failing due to element_info! API mismatch
- Will fix after more consolidations (old FEMBase 0.x API)
Result: 9 vendor packages consolidated (~6620 lines total)
Tests: 5 passing baseline maintained (heat tests need API fix)
