feat: Complete Phase 3.3 - Visualization & Model Cleanup System
Implemented automated post-processing capabilities for optimization workflows,
including publication-quality visualization and intelligent model cleanup to
manage disk space.
## New Features
### 1. Automated Visualization System (optimization_engine/visualizer.py)
**Capabilities**:
- 6 plot types: convergence, design space, parallel coordinates, sensitivity,
constraints, objectives
- Publication-quality output: PNG (300 DPI) + PDF (vector graphics)
- Auto-generated plot summary statistics
- Configurable output formats
**Plot Types**:
- Convergence: Objective vs trial number with running best
- Design Space: Parameter evolution colored by performance
- Parallel Coordinates: High-dimensional visualization
- Sensitivity Heatmap: Parameter correlation analysis
- Constraint Violations: Track constraint satisfaction
- Objective Breakdown: Multi-objective contributions
**Usage**:
```bash
# Standalone
python optimization_engine/visualizer.py substudy_dir png pdf
# Automatic (via config)
"post_processing": {"generate_plots": true, "plot_formats": ["png", "pdf"]}
```
### 2. Model Cleanup System (optimization_engine/model_cleanup.py)
**Purpose**: Reduce disk usage by deleting large CAD/FEM files from non-optimal trials
**Strategy**:
- Keep top-N best trials (configurable, default: 10)
- Delete large files: .prt, .sim, .fem, .op2, .f06, .dat, .bdf
- Preserve ALL results.json files (small, critical data)
- Dry-run mode for safety
**Usage**:
```bash
# Standalone
python optimization_engine/model_cleanup.py substudy_dir --keep-top-n 10
# Dry run (preview)
python optimization_engine/model_cleanup.py substudy_dir --dry-run
# Automatic (via config)
"post_processing": {"cleanup_models": true, "keep_top_n_models": 10}
```
**Typical Savings**: 50-90% disk space reduction
### 3. History Reconstruction Tool (optimization_engine/generate_history_from_trials.py)
**Purpose**: Generate history.json from older substudy formats
**Usage**:
```bash
python optimization_engine/generate_history_from_trials.py substudy_dir
```
## Configuration Integration
### JSON Configuration Format (NEW: post_processing section)
```json
{
"optimization_settings": { ... },
"post_processing": {
"generate_plots": true,
"plot_formats": ["png", "pdf"],
"cleanup_models": true,
"keep_top_n_models": 10,
"cleanup_dry_run": false
}
}
```
### Runner Integration (optimization_engine/runner.py:656-716)
Post-processing runs automatically after optimization completes:
- Generates plots using OptimizationVisualizer
- Runs model cleanup using ModelCleanup
- Handles exceptions gracefully with warnings
- Prints post-processing summary

### Study Organization
|
||||
|
||||
Each Atomizer substudy has its own Optuna database:
|
||||
|
||||
```
|
||||
studies/simple_beam_optimization/
|
||||
├── substudies/
|
||||
│ ├── full_optimization_50trials/
|
||||
│ │ ├── optuna_study.db # ← Optuna database (SQLite)
|
||||
│ │ ├── optuna_study.pkl # ← Optuna study object (pickle)
|
||||
│ │ ├── history.json # ← Atomizer history
|
||||
│ │ └── plots/ # ← Matplotlib plots
|
||||
│ └── validation_3trials/
|
||||
│ └── optuna_study.db
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "No studies found"
|
||||
|
||||
Make sure you're pointing to the correct database file:
|
||||
|
||||
```bash
|
||||
# Check if optuna_study.db exists
|
||||
ls studies/*/substudies/*/optuna_study.db
|
||||
|
||||
# Use absolute path if needed
|
||||
optuna-dashboard sqlite:///C:/Users/antoi/Documents/Atomaste/Atomizer/studies/simple_beam_optimization/substudies/full_optimization_50trials/optuna_study.db
|
||||
```
|
||||
|
||||
### Database Locked
|
||||
|
||||
If optimization is actively writing to the database:
|
||||
|
||||
```bash
|
||||
# Use read-only mode
|
||||
optuna-dashboard sqlite:///optuna_study.db?mode=ro
|
||||
```
|
||||
|
||||
### Port Already in Use
|
||||
|
||||
```bash
|
||||
# Use different port
|
||||
optuna-dashboard sqlite:///optuna_study.db --port 8888
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Example Workflow
|
||||
|
||||
```bash
|
||||
# 1. Start optimization
|
||||
python studies/simple_beam_optimization/run_optimization.py
|
||||
|
||||
# 2. In another terminal, launch Optuna dashboard
|
||||
cd studies/simple_beam_optimization/substudies/full_optimization_50trials
|
||||
optuna-dashboard sqlite:///optuna_study.db
|
||||
|
||||
# 3. Open browser to http://localhost:8080 and watch optimization live
|
||||
|
||||
# 4. After optimization completes, generate static plots
|
||||
python -m optimization_engine.visualizer studies/simple_beam_optimization/substudies/full_optimization_50trials png pdf
|
||||
|
||||
# 5. View final plots
|
||||
explorer studies/simple_beam_optimization/substudies/full_optimization_50trials/plots
|
||||
```

|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Matplotlib Import Error
|
||||
|
||||
**Problem**: `ImportError: No module named 'matplotlib'`
|
||||
|
||||
**Solution**: Install visualization dependencies
|
||||
```bash
|
||||
conda install -n atomizer matplotlib pandas "numpy<2" -y
|
||||
```
|
||||
|
||||
### Unicode Display Error
|
||||
|
||||
**Problem**: Checkmark character displays incorrectly in Windows console
|
||||
|
||||
**Status**: Fixed (replaced Unicode with "SUCCESS:")
|
||||
|
||||
### Missing history.json
|
||||
|
||||
**Problem**: Older substudies don't have `history.json`
|
||||
|
||||
**Solution**: Generate from trial results
|
||||
```bash
|
||||
python optimization_engine/generate_history_from_trials.py studies/beam/substudies/opt1
|
||||
```
|
||||
|
||||
### Cleanup Deleted Wrong Files
|
||||
|
||||
**Prevention**: ALWAYS use dry-run first!
|
||||
```bash
|
||||
python optimization_engine/model_cleanup.py <substudy> --dry-run
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Technical Details
|
||||
|
||||
### Dependencies
|
||||
|
||||
**Required**:
|
||||
- `matplotlib >= 3.10`
|
||||
- `numpy < 2.0` (pyNastran compatibility)
|
||||
- `pandas >= 2.3`
|
||||
- `optuna >= 3.0` (for dashboard)
|
||||
|
||||
**Optional**:
|
||||
- `optuna-dashboard` (for real-time monitoring)
|
||||
|
||||
### Performance
|
||||
|
||||
**Visualization**:
|
||||
- 50 trials: ~5-10 seconds
|
||||
- 100 trials: ~10-15 seconds
|
||||
- 500 trials: ~30-40 seconds
|
||||
|
||||
**Cleanup**:
|
||||
- Depends on file count and sizes
|
||||
- Typically < 1 minute for 100 trials

|
||||
## Assessment
|
||||
|
||||
### ✅ What's Working Well
|
||||
|
||||
1. **Substudy Isolation**: Each optimization run (substudy) is self-contained with its own trial directories, making it easy to compare different optimization strategies.
|
||||
|
||||
2. **Centralized Model**: The `model/` directory serves as a reference CAD/FEM model, which all substudies copy from.
|
||||
|
||||
3. **Configuration at Study Level**: `beam_optimization_config.json` provides the main configuration that substudies inherit from.
|
||||
|
||||
4. **Study-Level Documentation**: `README.md` and results markdown files at the study level provide high-level overviews.
|
||||
|
||||
5. **Clear Hierarchy**:
|
||||
- Study = Overall project (e.g., "optimize this beam")
|
||||
- Substudy = Specific optimization run (e.g., "50 trials with TPE sampler")
|
||||
- Trial = Individual design evaluation
|
||||
|
||||
### ⚠️ Issues Found
|
||||
|
||||
1. **Documentation Scattered**: Results documentation is at the study level (`OPTIMIZATION_RESULTS_50TRIALS.md`) but describes a specific substudy (`full_optimization_50trials`).
|
||||
|
||||
2. **Benchmarking Placement**: `substudies/benchmarking/` is not really a "substudy" - it's a validation step that should happen before optimization.
|
||||
|
||||
3. **Missing Substudy Metadata**: Some substudies lack their own README or summary files to explain what they tested.
|
||||
|
||||
4. **Inconsistent Naming**: `validation_3trials` vs `validation_4d_3trials` - unclear what distinguishes them without investigation.
|
||||
|
||||
5. **Study Metadata Incomplete**: `study_metadata.json` lists only "initial_exploration" substudy, but there are 5 substudies present.

### Key Changes
|
||||
|
||||
1. **Numbered Directories**: Indicate workflow sequence (setup → substudies → reports)
|
||||
|
||||
2. **Numbered Substudies**: Chronological naming (01_, 02_, 03_) makes progression clear
|
||||
|
||||
3. **Moved Benchmarking**: From `substudies/` to `1_setup/` (it's pre-optimization)
|
||||
|
||||
4. **Substudy-Level Documentation**: Each substudy has:
|
||||
- `README.md` - What was tested, parameters, hypothesis
|
||||
- `OPTIMIZATION_RESULTS.md` - Results and analysis
|
||||
|
||||
5. **Centralized Reports**: All comparative analysis and final recommendations in `3_reports/`
|
||||
|
||||
6. **Updated Metadata**: `study_metadata.json` tracks all substudies with status
|
||||

## Comparison: Current vs Proposed
|
||||
|
||||
| Aspect | Current | Proposed | Benefit |
|
||||
|--------|---------|----------|---------|
|
||||
| **Substudy naming** | Descriptive only | Numbered + descriptive | Chronological clarity |
|
||||
| **Documentation** | Mixed levels | Clear hierarchy | Easier to find results |
|
||||
| **Benchmarking** | In substudies/ | In 1_setup/ | Reflects true purpose |
|
||||
| **Model location** | study root | 1_setup/model/ | Grouped with setup |
|
||||
| **Reports** | Study root | 3_reports/ | Centralized analysis |
|
||||
| **Substudy docs** | Minimal | README + results | Self-documenting |
|
||||
| **Metadata** | Incomplete | All substudies tracked | Accurate status |

## Migration Guide
|
||||
|
||||
### Option 1: Reorganize Existing Study (Recommended)
|
||||
|
||||
**Steps**:
|
||||
1. Create new directory structure
|
||||
2. Move files to new locations
|
||||
3. Update `study_metadata.json`
|
||||
4. Update file references in documentation
|
||||
5. Create missing substudy READMEs
|
||||
|
||||
**Commands**:
|
||||
```bash
|
||||
# Create new structure
|
||||
mkdir -p studies/simple_beam_optimization/1_setup/model
|
||||
mkdir -p studies/simple_beam_optimization/1_setup/benchmarking
|
||||
mkdir -p studies/simple_beam_optimization/2_substudies
|
||||
mkdir -p studies/simple_beam_optimization/3_reports
|
||||
|
||||
# Move model
|
||||
mv studies/simple_beam_optimization/model/* studies/simple_beam_optimization/1_setup/model/
|
||||
|
||||
# Move benchmarking
|
||||
mv studies/simple_beam_optimization/substudies/benchmarking/* studies/simple_beam_optimization/1_setup/benchmarking/
|
||||
|
||||
# Rename and move substudies
|
||||
mv studies/simple_beam_optimization/substudies/initial_exploration studies/simple_beam_optimization/2_substudies/01_initial_exploration
|
||||
mv studies/simple_beam_optimization/substudies/validation_3trials studies/simple_beam_optimization/2_substudies/02_validation_3d_3trials
|
||||
mv studies/simple_beam_optimization/substudies/validation_4d_3trials studies/simple_beam_optimization/2_substudies/03_validation_4d_3trials
|
||||
mv studies/simple_beam_optimization/substudies/full_optimization_50trials studies/simple_beam_optimization/2_substudies/04_full_optimization_50trials
|
||||
|
||||
# Move reports
|
||||
mv studies/simple_beam_optimization/COMPREHENSIVE_BENCHMARK_RESULTS.md studies/simple_beam_optimization/3_reports/
|
||||
mv studies/simple_beam_optimization/OPTIMIZATION_RESULTS_50TRIALS.md studies/simple_beam_optimization/2_substudies/04_full_optimization_50trials/
|
||||
|
||||
# Clean up
|
||||
rm -rf studies/simple_beam_optimization/substudies/
|
||||
rm -rf studies/simple_beam_optimization/model/
|
||||
```
|
||||
|
||||
### Option 2: Apply to Future Studies Only
|
||||
|
||||
Keep existing study as-is, apply new organization to future studies.
|
||||
|
||||
**When to Use**:
|
||||
- Current study is complete and well-understood
|
||||
- Reorganization would break existing scripts/references
|
||||
- Want to test new organization before migrating
|
||||
|

|
||||
|
||||
## Best Practices
|
||||
|
||||
### Study-Level Files
|
||||
|
||||
**Required**:
|
||||
- `README.md` - High-level overview, purpose, design variables, objectives
|
||||
- `study_metadata.json` - Metadata, status, substudy registry
|
||||
- `beam_optimization_config.json` - Main configuration (inheritable)
|
||||
- `run_optimization.py` - Study-specific runner script
|
||||
|
||||
**Optional**:
|
||||
- `CHANGELOG.md` - Track configuration changes across substudies
|
||||
- `LESSONS_LEARNED.md` - Engineering insights, dead ends avoided
|
||||
|
||||
### Substudy-Level Files
|
||||
|
||||
**Required** (Generated by Runner):
|
||||
- `trial_XXX/` - Trial directories with CAD/FEM files and results.json
|
||||
- `history.json` - Full optimization history
|
||||
- `best_trial.json` - Best trial metadata
|
||||
- `optuna_study.pkl` - Optuna study object
|
||||
- `config.json` - Substudy-specific configuration
|
||||
|
||||
**Required** (User-Created):
|
||||
- `README.md` - Purpose, hypothesis, parameter choices
|
||||
|
||||
**Optional** (Auto-Generated):
|
||||
- `plots/` - Visualization plots (if post_processing.generate_plots = true)
|
||||
- `cleanup_log.json` - Model cleanup statistics (if post_processing.cleanup_models = true)
|
||||
|
||||
**Optional** (User-Created):
|
||||
- `OPTIMIZATION_RESULTS.md` - Detailed analysis and interpretation
|
||||
|
||||
### Trial-Level Files
|
||||
|
||||
**Always Kept** (Small, Critical):
|
||||
- `results.json` - Extracted objectives, constraints, design variables
|
||||
|
||||
**Kept for Top-N Trials** (Large, Useful):
|
||||
- `Beam.prt` - CAD model
|
||||
- `Beam_sim1.sim` - Simulation setup
|
||||
- `beam_sim1-solution_1.op2` - FEA results (binary)
|
||||
- `beam_sim1-solution_1.f06` - FEA results (text)
|
||||
|
||||
**Cleaned for Poor Trials** (Large, Less Useful):
|
||||
- All `.prt`, `.sim`, `.fem`, `.op2`, `.f06` files deleted
|
||||
- Only `results.json` preserved
|
||||
|
||||

|
||||
|
||||
## Naming Conventions
|
||||
|
||||
### Substudy Names
|
||||
|
||||
**Format**: `NN_descriptive_name`
|
||||
|
||||
**Examples**:
|
||||
- `01_initial_exploration` - First exploration of design space
|
||||
- `02_validation_3d_3trials` - Validate 3 design variables work
|
||||
- `03_validation_4d_3trials` - Validate 4 design variables work
|
||||
- `04_full_optimization_50trials` - Full optimization run
|
||||
- `05_refined_search_30trials` - Refined search in promising region
|
||||
- `06_sensitivity_analysis` - Parameter sensitivity study
|
||||
|
||||
**Guidelines**:
|
||||
- Start with two-digit number (01, 02, ..., 99)
|
||||
- Use underscores for spaces
|
||||
- Be concise but descriptive
|
||||
- Include trial count if relevant
|
||||
|
||||
### Study Names
|
||||
|
||||
**Format**: `descriptive_name` (no numbering)
|
||||
|
||||
**Examples**:
|
||||

## Workflow Integration
|
||||
|
||||
### Creating a New Substudy
|
||||
|
||||
**Steps**:
|
||||
1. Determine substudy number (next in sequence)
|
||||
2. Create substudy README.md with purpose and changes
|
||||
3. Update configuration if needed
|
||||
4. Run optimization:
|
||||
```bash
|
||||
python run_optimization.py --substudy-name "05_refined_search_30trials"
|
||||
```
|
||||
5. After completion:
|
||||
- Review results
|
||||
- Update substudy README.md with findings
|
||||
- Create OPTIMIZATION_RESULTS.md if significant
|
||||
- Update study_metadata.json
|
||||
|
||||
### Comparing Substudies
|
||||
|
||||
**Create Comparison Report**:
|
||||
```markdown
|
||||
# Substudy Comparison
|
||||
|
||||
| Substudy | Trials | Best Obj | Feasible | Key Finding |
|
||||
|----------|--------|----------|----------|-------------|
|
||||
| 01_initial_exploration | 10 | 1250.3 | 0/10 | Design space too large |
|
||||
| 02_validation_3d_3trials | 3 | 1180.5 | 0/3 | 3D updates work |
|
||||
| 03_validation_4d_3trials | 3 | 1120.2 | 0/3 | hole_count updates work |
|
||||
| 04_full_optimization_50trials | 50 | 842.6 | 0/50 | No feasible designs found |
|
||||
|
||||
**Conclusion**: Constraint appears infeasible. Recommend relaxing displacement limit.
|
||||
```

||||
3. **Version Control**: Clear history through numbered substudies
|
||||
4. **Scalability**: Works for 5 substudies or 50
|
||||
|
||||
### For Collaboration
|
||||
|
||||
1. **Onboarding**: New team members can understand study progression quickly
|
||||
2. **Documentation**: Substudy READMEs explain decisions made

## FAQ
|
||||
|
||||
### Q: Should I reorganize my existing study?
|
||||
|
||||
**A**: Only if:
|
||||
- Study is still active (more substudies planned)
|
||||
- Current organization is causing confusion
|
||||
- You have time to update documentation references
|
||||
|
||||
Otherwise, apply to future studies only.
|
||||
|
||||
### Q: What if my substudy doesn't have a fixed trial count?
|
||||
|
||||
**A**: Use descriptive name instead:
|
||||
- `05_refined_search_until_feasible`
|
||||
- `06_sensitivity_sweep`
|
||||
- `07_validation_run`
|
||||
|
||||
### Q: Can I delete old substudies?
|
||||
|
||||
**A**: Generally no. Keep for:
|
||||
- Historical record
|
||||
- Lessons learned
|
||||
- Reproducibility
|
||||
|
||||
If disk space is critical:
|
||||
- Use model cleanup to delete CAD/FEM files
|
||||
- Archive old substudies to external storage
|
||||
- Keep metadata and results.json files
|
||||
|
||||
### Q: Should benchmarking be a substudy?
|
||||
|
||||
**A**: No. Benchmarking validates the baseline model before optimization. It belongs in `1_setup/benchmarking/`.
|
||||
|
||||
### Q: How do I handle multi-stage optimizations?
|
||||
|
||||
**A**: Create separate substudies:
|
||||
- `05_stage1_meet_constraint_20trials`
|
||||
- `06_stage2_minimize_mass_30trials`
|
||||
|
||||
Document the relationship in substudy READMEs.

## Summary
|
||||
|
||||
**Current Organization**: Functional but has room for improvement
|
||||
- ✅ Substudy isolation works well
|
||||
- ⚠️ Documentation scattered across levels
|
||||
- ⚠️ Chronology unclear from names alone
|
||||
|
||||
**Proposed Organization**: Clearer hierarchy and progression
|
||||
- 📁 `1_setup/` - Pre-optimization (model, benchmarking)
|
||||
- 📁 `2_substudies/` - Numbered optimization runs
|
||||
- 📁 `3_reports/` - Comparative analysis
|
||||
|
||||
**Next Steps**:
|
||||
1. Decide: Reorganize existing study or apply to future only
|
||||
2. If reorganizing: Follow migration guide
|
||||
3. Update `study_metadata.json` with all substudies
|
||||
4. Create substudy README templates
|
||||
5. Document lessons learned in study-level docs
|
||||
|
||||
**Bottom Line**: The proposed organization makes it easier to understand what was done, why it was done, and what was learned.
