Design Variables

• support_angle
• tip_thickness

Objectives

• stiffness
• mass

Constraints

• mass_limit

Usage with AtomizerField

1. Parse Training Data

cd Atomizer-Field
python batch_parser.py --data-dir "C:\Users\antoi\Documents\Atomaste\Atomizer\atomizer_field_training_data\bracket_stiffness_optimization_atomizerfield"

This converts BDF/OP2 files to PyTorch Geometric format.

2. Validate Parsed Data

python validate_parsed_data.py

3. Train Neural Network

python train.py --data-dir "training_data/parsed/" --epochs 200

4. Use Trained Model in Atomizer

cd ../Atomizer
python run_optimization.py --config studies/bracket_stiffness_optimization_atomizerfield/workflow_config.json --use-neural

File Formats

• BDF (.bdf): Nastran Bulk Data File - contains mesh, materials, loads, BCs
• OP2 (.op2): Nastran Output2 - binary results with displacements, stresses, etc.
• metadata.json: Human-readable trial metadata
