feat: Add MCP build_optimization_config tool

Browse Source 
Integrate OP2 data extraction with optimization config builder:
- Add build_optimization_config() MCP tool
- Add list_optimization_options() helper
- Add format_optimization_options_for_llm() formatter
- Update MCP tools documentation with full API details
- Test with bracket example, generates valid config

Features:
- Discovers design variables from FEA model
- Lists 4 available objectives (mass, stress, displacement, volume)
- Lists 4 available constraints (stress/displacement/mass limits)
- Validates user selections against model
- Generates complete optimization_config.json

Tested with examples/bracket/Bracket_sim1.sim:
- Found 4 design variables (support_angle, tip_thickness, p3, support_blend_radius)
- Created config with 2 objectives, 2 constraints, 150 trials

### 2. Build Optimization Config (PLANNED)
### 2. Build Optimization Config (`optimization_config.py`) ✅ IMPLEMENTED
**Purpose**: Generate `optimization_config.json` from natural language requirements.
**Purpose**: Generate `optimization_config.json` from user selections of objectives, constraints, and design variables.
**Function**: `build_optimization_config(requirements: str, model_info: Dict) -> Dict[str, Any]`
**Functions**:
- `build_optimization_config(...)` - Create complete optimization configuration
- `list_optimization_options(sim_file_path)` - List all available options for a model
- `format_optimization_options_for_llm(options)` - Format options as Markdown
**Planned Features**:
- Parse LLM instructions ("minimize stress while reducing mass")
- Select appropriate result extractors
- Suggest reasonable parameter bounds
- Generate complete config for optimization engine
**What it does**:
- Discovers available design variables from the FEA model
- Lists available objectives (minimize mass, stress, displacement, volume)
- Lists available constraints (max stress, max displacement, mass limits)
- Builds a complete `optimization_config.json` based on user selections
- Validates that all selections are valid for the model
**Usage Example**:
```python
from mcp_server.tools import build_optimization_config, list_optimization_options
# Step 1: List available options
options = list_optimization_options("examples/bracket/Bracket_sim1.sim")
print(f"Available design variables: {len(options['available_design_variables'])}")
# Step 2: Build configuration
result = build_optimization_config(
sim_file_path="examples/bracket/Bracket_sim1.sim",
design_variables=[
{'name': 'tip_thickness', 'lower_bound': 15.0, 'upper_bound': 25.0},
{'name': 'support_angle', 'lower_bound': 20.0, 'upper_bound': 40.0}
],
objectives=[
{'objective_key': 'minimize_mass', 'weight': 5.0},
{'objective_key': 'minimize_max_stress', 'weight': 10.0}
],
constraints=[
{'constraint_key': 'max_displacement_limit', 'limit_value': 1.0},
{'constraint_key': 'max_stress_limit', 'limit_value': 200.0}
],
optimization_settings={
'n_trials': 150,
'sampler': 'TPE'
}
)
if result['status'] == 'success':
print(f"Config saved to: {result['config_file']}")
```
**Command Line Usage**:
```bash
python mcp_server/tools/optimization_config.py examples/bracket/Bracket_sim1.sim
```
**Available Objectives**:
- `minimize_mass`: Minimize total mass (weight reduction)
- `minimize_max_stress`: Minimize maximum von Mises stress
- `minimize_max_displacement`: Minimize maximum displacement (increase stiffness)
- `minimize_volume`: Minimize total volume (material usage)
**Available Constraints**:
- `max_stress_limit`: Maximum allowable von Mises stress
- `max_displacement_limit`: Maximum allowable displacement
- `min_mass_limit`: Minimum required mass (structural integrity)
- `max_mass_limit`: Maximum allowable mass (weight budget)
**Output**: Creates `optimization_config.json` with:
- Design variable definitions with bounds
- Multi-objective configuration with weights
- Constraint definitions with limits
- Optimization algorithm settings (trials, sampler)
