- Added 1111 lines of mesh reading code to src/readers/
- ABAQUS .inp format support (6 files: parse_mesh, parse_model, keywords, etc.)
- Code Aster .med format support (3 files: read_aster_mesh, read_aster_results)
- Modernized Julia 0.x → 1.x syntax:
* Nullable{T} → Union{T, Nothing}
* get(nullable) → direct field access
- Added Logging stdlib to Project.toml dependencies
- Functions verified: abaqus_read_mesh, aster_read_mesh
Result: 7 vendor packages consolidated (~6400 lines total)
FEMBasis, FEMBase, FEMQuad, FEMSparse, AbaqusReader, AsterReader
Tests: 5 passing (baseline maintained)
