```python
class ExtractorOrchestrator:
"""

"""

## Complete Workflow Example
### User Request (Natural Language)
> "Extract displacement from OP2, normalize by 5mm maximum allowed, and minimize"
### Phase 2.7: LLM Analysis
```json
{
"engineering_features": [
{
"action": "extract_displacement",
"domain": "result_extraction",
"description": "Extract displacement results from OP2 file",
"params": {
"result_type": "displacement"
}
}
],
"inline_calculations": [
{
"action": "find_maximum",
"params": {"input": "max_displacement"}
},
{
"action": "normalize",
"params": {
"input": "max_displacement",
"reference": "max_allowed_disp",
"value": 5.0
}
}
],
"post_processing_hooks": [
{
"action": "weighted_objective",
"params": {
"inputs": ["norm_disp"],
"weights": [1.0],
"objective": "minimize"
}
}
]
}
```
### Phase 3.1: Orchestrator Processing
```python
# Initialize orchestrator
orchestrator = ExtractorOrchestrator()
# Process LLM output
extractors = orchestrator.process_llm_workflow(llm_output)
# Result: extract_displacement.py generated
```
### Phase 3.0: Generated Extractor Code
**File**: `result_extractors/generated/extract_displacement.py`
```python
"""
Extract displacement results from OP2 file
Auto-generated by Atomizer Phase 3 - pyNastran Research Agent
Pattern: displacement
Result Type: displacement
API: model.displacements[subcase]
"""
from pathlib import Path
from typing import Dict, Any
import numpy as np
from pyNastran.op2.op2 import OP2
def extract_displacement(op2_file: Path, subcase: int = 1):
"""Extract displacement results from OP2 file."""
model = OP2()
model.read_op2(str(op2_file))
disp = model.displacements[subcase]
itime = 0 # static case
# Extract translation components
txyz = disp.data[itime, :, :3]
total_disp = np.linalg.norm(txyz, axis=1)
max_disp = np.max(total_disp)
node_ids = [nid for (nid, grid_type) in disp.node_gridtype]
max_disp_node = node_ids[np.argmax(total_disp)]
return {
'max_displacement': float(max_disp),
'max_disp_node': int(max_disp_node),
'max_disp_x': float(np.max(np.abs(txyz[:, 0]))),
'max_disp_y': float(np.max(np.abs(txyz[:, 1]))),
'max_disp_z': float(np.max(np.abs(txyz[:, 2])))
}
```
### Execution on Real OP2
```python
# Execute on bracket OP2
result = orchestrator.execute_extractor(
'extract_displacement',
Path('tests/bracket_sim1-solution_1.op2'),
subcase=1
)
# Result:
# {
# 'max_displacement': 0.361783,
# 'max_disp_node': 91,
# 'max_disp_x': 0.002917,
# 'max_disp_y': 0.074244,
# 'max_disp_z': 0.354083
# }
```
### Phase 2.8: Inline Calculations (Auto-Generated)
```python
# Auto-generated by Phase 2.8
max_disp = result['max_displacement'] # 0.361783
max_allowed_disp = 5.0
norm_disp = max_disp / max_allowed_disp # 0.072357
```
### Phase 2.9: Post-Processing Hook (Auto-Generated)
```python
# Auto-generated hook in plugins/post_calculation/
def weighted_objective_hook(context):
calculations = context.get('calculations', {})
norm_disp = calculations.get('norm_disp')
objective = 1.0 * norm_disp
return {'weighted_objective': objective}
# Result: weighted_objective = 0.072357
```
### Final Result → Optuna
```
Trial N completed
Objective value: 0.072357
```
**ZERO manual coding from user request to Optuna trial!** 🚀
## Key Integration Points
### 1. LLM → Orchestrator
**Input** (Phase 2.7 output):
```json
{
"engineering_features": [
{
"action": "extract_1d_element_forces",
"domain": "result_extraction",
"params": {
"element_types": ["CBAR"],
"direction": "Z"
}
}
]
}
```
**Processing**:
```python
for feature in llm_output['engineering_features']:
if feature['domain'] == 'result_extraction':
extractor = orchestrator.generate_extractor_from_feature(feature)
```
### 2. Orchestrator → Research Agent
**Request to Phase 3**:
```python
research_request = {
'action': 'extract_1d_element_forces',
'domain': 'result_extraction',
'description': 'Extract element forces from CBAR in Z direction',
'params': {
'element_types': ['CBAR'],
'direction': 'Z'
}
}
pattern = research_agent.research_extraction(research_request)
code = research_agent.generate_extractor_code(research_request)
```
**Response**:
- `pattern`: ExtractionPattern(name='cbar_force', ...)
- `code`: Complete Python module string
### 3. Generated Code → Execution
**Dynamic Loading**:
```python
# Import the generated module
spec = importlib.util.spec_from_file_location(name, file_path)
module = importlib.util.module_from_spec(spec)
spec.loader.exec_module(module)
# Get the function
extractor_func = getattr(module, function_name)
# Execute
result = extractor_func(op2_file, **params)
```
### 4. Smart Parameter Filtering
Different extraction patterns need different parameters:
```python
if pattern_name == 'displacement':
# Only pass subcase (no direction, element_type, etc.)
params = {k: v for k, v in kwargs.items() if k in ['subcase']}
elif pattern_name == 'cbar_force':
# Pass direction and subcase
params = {k: v for k, v in kwargs.items() if k in ['direction', 'subcase']}
elif pattern_name == 'solid_stress':
# Pass element_type and subcase
params = {k: v for k, v in kwargs.items() if k in ['element_type', 'subcase']}
```
This prevents errors from passing irrelevant parameters!
## Testing
### Test File: [tests/test_phase_3_1_integration.py](../tests/test_phase_3_1_integration.py)
**Test 1: End-to-End Workflow**
```
STEP 1: Phase 2.7 LLM Analysis
- 1 engineering feature
- 2 inline calculations
- 1 post-processing hook
STEP 2: Phase 3.1 Orchestrator
- Generated 1 extractor (extract_displacement)
STEP 3: Execution on Real OP2
- OP2 File: bracket_sim1-solution_1.op2
- Result: max_displacement = 0.361783mm at node 91
STEP 4: Inline Calculations
- norm_disp = 0.361783 / 5.0 = 0.072357
STEP 5: Post-Processing Hook
- weighted_objective = 0.072357
Result: PASSED!
```
**Test 2: Multiple Extractors**
```
LLM Output:
- extract_displacement
- extract_solid_stress
Result: Generated 2 extractors
- extract_displacement (displacement pattern)
- extract_solid_stress (solid_stress pattern)
Result: PASSED!
```
## Benefits
### 1. Complete Automation
**Before** (Manual workflow):
```
1. User describes optimization
2. Engineer manually writes OP2 extractor
3. Engineer manually writes calculations
4. Engineer manually writes objective function
5. Engineer integrates with optimization runner
Time: Hours to days
```
**After** (Automated workflow):
```
1. User describes optimization in natural language
2. System generates ALL code automatically
Time: Seconds
```
### 2. Zero Learning Curve
Users don't need to know:
- ❌ pyNastran API
- ❌ OP2 file structure
- ❌ Python coding
- ❌ Optimization framework
They only need to describe **what they want** in natural language!
### 3. Correct by Construction
Generated code uses:
- ✅ Proven extraction patterns from research agent
- ✅ Correct API paths from documentation
- ✅ Proper data structure access
- ✅ Error handling and validation
No manual bugs!
### 4. Extensible
Adding new extraction patterns:
1. Research agent learns from pyNastran docs
2. Stores pattern in knowledge base
3. Available immediately for all future requests
## Future Enhancements
### Phase 3.2: Optimization Runner Integration
**Next Step**: Integrate orchestrator with optimization runner for complete automation:
```python
class OptimizationRunner:
def __init__(self, llm_output: Dict):
# Process LLM output
self.orchestrator = ExtractorOrchestrator()
self.extractors = self.orchestrator.process_llm_workflow(llm_output)
# Generate inline calculations (Phase 2.8)
self.calculator = InlineCodeGenerator()
self.calculations = self.calculator.generate(llm_output)
# Generate hooks (Phase 2.9)
self.hook_gen = HookGenerator()
self.hooks = self.hook_gen.generate_lifecycle_hooks(llm_output)
def run_trial(self, trial_number, design_variables):
# Run NX solve
op2_file = self.nx_solver.run(...)
# Extract results using generated extractors
results = {}
for extractor_name in self.extractors:
results.update(
self.orchestrator.execute_extractor(extractor_name, op2_file)
)
# Execute inline calculations
calculations = self.calculator.execute(results)
# Execute hooks
hook_results = self.hook_manager.execute_hooks('post_calculation', {
'results': results,
'calculations': calculations
})
# Return objective
return hook_results.get('objective')
```
### Phase 3.3: Error Recovery
- Detect extraction failures
- Attempt pattern variations
- Fallback to generic extractors
- Log failures for pattern learning
### Phase 3.4: Performance Optimization
- Cache OP2 reading for multiple extractions
- Parallel extraction for multiple result types
- Reuse loaded models across trials
### Phase 3.5: Pattern Expansion
- Learn patterns for more element types
- Composite stress/strain
- Eigenvectors/eigenvalues
- F06 result extraction
- XDB database extraction
