## Overview

Atomizer is a next-generation optimization framework for Siemens NX that combines:

- **LLM-Driven Configuration**: Use natural language to set up complex optimizations
- **Advanced Algorithms**: Optuna-powered TPE, Gaussian Process surrogates, multi-fidelity optimization
- **Real-Time Monitoring**: Interactive dashboards with live updates
- **Flexible Architecture**: Pluggable result extractors for any FEA analysis type
- **MCP Integration**: Extensible via Model Context Protocol

## Quick Start

### Prerequisites

- **Siemens NX 2412** with NX Nastran solver
- **Python 3.10+** (recommend Anaconda)
- **Node.js 18+** (for dashboard frontend)

### Installation

1. **Clone the repository**:
   ```bash
   git clone https://github.com/Anto01/Atomizer.git
   cd Atomizer
   ```

2. **Create Python environment**:
   ```bash
   conda create -n atomizer python=3.10
   conda activate atomizer
   ```

3. **Install dependencies**:
   ```bash
   pip install -e .
   # For development tools:
   pip install -e ".[dev]"
   # For MCP server:
   pip install -e ".[mcp]"
   ```

4. **Configure NX path** (edit `config/nx_config.json`):
   ```json
   {
     "nx_executable": "C:/Program Files/Siemens/NX2412/NXBIN/ugraf.exe",
     "python_env": "C:/Users/YourName/anaconda3/envs/atomizer/python.exe"
   }
   ```

### Basic Usage

#### 1. Conversational Setup (via MCP)

```
You: My FEA is in C:\Projects\Bracket\analysis.sim, please import its features.

AI: I've analyzed your model:
    - Solution: Static Analysis (NX Nastran)
    - Expressions: wall_thickness (5mm), hole_diameter (10mm)
    - Mesh: 8234 nodes, 4521 elements

    Which parameters would you like to optimize?

You: Optimize wall_thickness and hole_diameter to minimize max stress while keeping mass low.

AI: Configuration created! Ready to start optimization with 100 iterations.
    Would you like to review the config or start now?

You: Start it!

AI: Optimization launched! 🚀
    Dashboard: http://localhost:8080/dashboard
```

#### 2. Manual Configuration (JSON)

Create `optimization_config.json`:

```json
{
  "design_variables": {
    "wall_thickness": {
      "low": 3.0,
      "high": 8.0,
      "enabled": true
    }
  },
  "objectives": {
    "metrics": {
      "max_stress": {
        "weight": 10,
        "target": 200,
        "extractor": "nastran_stress"
      }
    }
  },
  "nx_settings": {
    "sim_path": "C:/Projects/Bracket/analysis.sim",
    "solution_name": "Solution 1"
  }
}
```

Run optimization:
```bash
python -m optimization_engine.run_optimizer --config optimization_config.json
```
