Backend Integration Plan

Objective

Implement the backend logic required to support the advanced dashboard features, including study creation, real-time data streaming, 3D mesh conversion, and report generation.

1. Enhanced WebSocket Real-Time Streaming

File: atomizer-dashboard/backend/api/websocket/optimization_stream.py

Tasks

• Update OptimizationFileHandler to watch for pareto_front updates.
• Update OptimizationFileHandler to watch for optimizer_state updates.
• Implement broadcasting logic for new event types: pareto_front, optimizer_state.

2. Study Creation API

File: atomizer-dashboard/backend/api/routes/optimization.py

Tasks

• Implement POST /api/optimization/studies endpoint.
• Add logic to handle multipart/form-data (config + files).
• Create study directory structure (1_setup, 2_results, etc.).
• Save uploaded files (.prt, .sim, .fem) to 1_setup/model/.
• Save configuration to 1_setup/optimization_config.json.

3. 3D Mesh Visualization API

File: atomizer-dashboard/backend/api/routes/optimization.py & optimization_engine/mesh_converter.py

Tasks

• Create optimization_engine/mesh_converter.py utility.
  • Implement convert_to_gltf(bdf_path, op2_path, output_path) function.
  • Use pyNastran to read BDF/OP2.
  • Use trimesh (or custom logic) to export GLTF.
• Implement POST /api/optimization/studies/{study_id}/convert-mesh endpoint.
• Implement GET /api/optimization/studies/{study_id}/mesh/{filename} endpoint.

4. Report Generation API

File: atomizer-dashboard/backend/api/routes/optimization.py & optimization_engine/report_generator.py

Tasks

• Create optimization_engine/report_generator.py utility.
  • Implement generate_report(study_id, format, include_llm) function.
  • Use markdown and weasyprint (optional) for rendering.
• Implement POST /api/optimization/studies/{study_id}/generate-report endpoint.
• Implement GET /api/optimization/studies/{study_id}/reports/{filename} endpoint.

5. Dependencies

File: atomizer-dashboard/backend/requirements.txt

Tasks

• Add python-multipart (for file uploads).
• Add pyNastran (for mesh conversion).
• Add trimesh (optional, for GLTF export).
• Add markdown (for report generation).
• Add weasyprint (optional, for PDF generation).

Execution Order

1. Dependencies: Update requirements.txt and install packages.
2. Study Creation: Implement the POST endpoint to enable the Configurator.
3. WebSocket: Enhance the stream to support advanced visualizations.
4. 3D Pipeline: Build the mesh converter and API endpoints.
5. Reporting: Build the report generator and API endpoints.
