Atomizer/examples/bracket/bracket_sim1-solution_1.log
Claude 4afb46327a feat: Add complete Bracket example with validated OP2 extraction 
Added complete working example with all NX result files for testing
and validation of the OP2 result extractor.

Files Added (examples/bracket/):
- Bracket.prt: Part geometry with expressions
- Bracket_sim1.sim: Simulation definition (SOL 101 Linear Statics)
- Bracket_fem1.fem: Finite element mesh
- bracket_sim1-solution_1.op2: Binary results (666 KB)
- bracket_sim1-solution_1.f06: ASCII results log
- bracket_sim1-solution_1.dat: Nastran input deck
- Supporting files: .diag, .f04, .log, .html, .png

Validated Results from OP2:
✓ Max Displacement: 0.362 mm (node 91)
  - Primary direction: -Z (-0.354 mm)
  - Load application point

✓ Max von Mises Stress: 122.91 MPa (element 79, CHEXA)
  - Material: Aluminum 6061-T6 (yield = 276 MPa)
  - Safety Factor: 2.25 ✅ SAFE
  - Well below yield strength

Units Handling:
- NX units: mm, mN (milli-newton), kg
- Stress in OP2: mN/mm² = kPa
- Conversion required: kPa / 1000 = MPa
- Displacement: mm (direct)

Model Properties:
- Analysis Type: SOL 101 Linear Statics
- Elements: 585 (CHEXA hexahedral)
- Load: ~1000 N in -Z direction (3 application points)
- Constraints: Fixed supports at base
- Material: Al 6061-T6

Optimization Potential:
Current design has good margins:
- Displacement: 0.36 mm (could allow up to ~1.0 mm)
- Stress: 122.91 MPa (could allow up to ~200 MPa)
→ Weight reduction opportunity while maintaining safety!

This validates:
- pyNastran OP2 extraction works correctly
- Units conversion handling (mN → N, kPa → MPa)
- Multi-objective optimization is feasible
- Example ready for testing optimization workflow
