Instead of navigating complex GUIs and manually configuring optimization parameters, engineers describe what they want to optimize in natural language, and Claude (the AI) orchestrates the entire workflow. +Atomizer is an **intelligent optimization engine and NX configurator** designed to bridge the gap between state-of-the-art simulation methods and performant, production-ready FEA workflows. It's not about CAD manipulation or mesh generation - those are setup concerns. Atomizer focuses on what matters: **making advanced simulation methods accessible and effective**. -### The Core Philosophy: "Talk, Don't Click" +### The Core Problem We Solve -Traditional structural optimization is a fragmented, manual, expert-intensive process. Engineers spend 80% of their time on: -- Setup and file management -- Configuring numerical parameters they may not fully understand -- Interpreting cryptic solver outputs -- Generating reports manually +State-of-the-art optimization algorithms exist in academic papers. Performant FEA simulations exist in commercial tools like NX Nastran. But bridging these two worlds requires: +- Deep knowledge of optimization theory (TPE, CMA-ES, Bayesian methods) +- Understanding of simulation physics and solver behavior +- Experience with what works for different problem types +- Infrastructure for running hundreds of automated trials -Atomizer eliminates this friction entirely. The user says something like: -> "Optimize this bracket for minimum mass while keeping stress below 200 MPa" +Most engineers don't have time to become experts in all these domains. **Atomizer is that bridge.** -And Atomizer: -1. Inspects the CAD model to find adjustable parameters -2. Generates an optimization configuration -3. Runs hundreds of FEA simulations automatically -4. Trains neural network surrogates for acceleration -5. Analyzes results and generates publication-ready reports +### The Core Philosophy: "Optimize Smarter, Not Harder" + +Traditional structural optimization is painful because: +- Engineers pick algorithms without knowing which is best for their problem +- Every new study starts from scratch - no accumulated knowledge +- Commercial tools offer generic methods, not physics-appropriate ones +- Simulation expertise and optimization expertise rarely coexist + +Atomizer solves this by: +1. **Characterizing each study** to understand its optimization landscape +2. **Selecting methods automatically** based on problem characteristics +3. **Learning from every study** what works and what doesn't +4. **Building a knowledge base** of parameter-performance relationships + +### What Atomizer Is NOT + +- It's not a CAD tool - geometry modeling happens in NX +- It's not a mesh generator - meshing is handled by NX Pre/Post +- It's not replacing the engineer's judgment - it's amplifying it +- It's not a black box - every decision is traceable and explainable ### Target Audience -- **FEA Engineers** working with Siemens NX and NX Nastran -- **Aerospace & Automotive** structural designers -- **Research institutions** doing parametric studies -- **Anyone** who's ever thought "I wish I could just tell my CAE software what I want" +- **FEA Engineers** who want to run serious optimization campaigns +- **Simulation specialists** tired of manual trial-and-error +- **Research teams** exploring design spaces systematically +- **Anyone** who needs to find optimal designs faster ### Key Differentiators from Commercial Tools | Feature | OptiStruct/HEEDS | optiSLang | Atomizer | |---------|------------------|-----------|----------| -| Interface | GUI-based | GUI-based | **Conversational AI** | -| Learning curve | Weeks | Weeks | **Minutes** | -| Neural surrogates | Limited | Basic | **Full GNN + MLP + Gradient** | -| Customization | Scripts | Workflows | **Natural language** | -| Documentation | Manual | Manual | **Self-generating** | -| Context memory | None | None | **LAC persistent learning** | +| Algorithm selection | Manual | Manual | **Automatic (IMSO)** | +| Learning from history | None | None | **LAC persistent memory** | +| Study characterization | Basic | Basic | **Full landscape analysis** | +| Neural acceleration | Limited | Basic | **GNN + MLP + Gradient** | +| Protocol validation | None | None | **Research → Review → Approve** | +| Documentation source | Static manuals | Static manuals | **MCP-first, live lookups** | --- -# PART 2: TECHNICAL ARCHITECTURE +# PART 2: STUDY CHARACTERIZATION & PERFORMANCE LEARNING -## The Protocol Operating System (POS) +## The Heart of Atomizer: Understanding What Works -Atomizer doesn't improvise - it operates through a structured 4-layer protocol system that ensures consistency and traceability. +The most valuable thing Atomizer does is **learn what makes studies succeed**. This isn't just recording results - it's building a deep understanding of the relationship between: + +- **Study parameters** (geometry type, design variable count, constraint complexity) +- **Optimization methods** (which algorithm, what settings) +- **Performance outcomes** (convergence speed, solution quality, feasibility rate) + +### Study Characterization Process + +When Atomizer runs an optimization, it doesn't just optimize - it **characterizes**: ``` ┌─────────────────────────────────────────────────────────────────┐ -│ Layer 0: BOOTSTRAP (.claude/skills/00_BOOTSTRAP.md) │ -│ Purpose: Task routing, quick reference, session initialization │ -└─────────────────────────────────────────────────────────────────┘ - ▼ -┌─────────────────────────────────────────────────────────────────┐ -│ Layer 1: OPERATIONS (docs/protocols/operations/OP_*.md) │ -│ OP_01: Create Study OP_02: Run Optimization │ -│ OP_03: Monitor OP_04: Analyze Results │ -│ OP_05: Export Data OP_06: Troubleshoot │ -│ OP_07: Disk Optimization │ -└─────────────────────────────────────────────────────────────────┘ - ▼ -┌─────────────────────────────────────────────────────────────────┐ -│ Layer 2: SYSTEM (docs/protocols/system/SYS_*.md) │ -│ SYS_10: IMSO (adaptive) SYS_11: Multi-objective │ -│ SYS_12: Extractors SYS_13: Dashboard │ -│ SYS_14: Neural Accel SYS_15: Method Selector │ -│ SYS_16: Study Insights SYS_17: Context Engineering │ -└─────────────────────────────────────────────────────────────────┘ - ▼ -┌─────────────────────────────────────────────────────────────────┐ -│ Layer 3: EXTENSIONS (docs/protocols/extensions/EXT_*.md) │ -│ EXT_01: Create Extractor EXT_02: Create Hook │ -│ EXT_03: Create Protocol EXT_04: Create Skill │ +│ STUDY CHARACTERIZATION │ +├─────────────────────────────────────────────────────────────────┤ +│ │ +│ PROBLEM FINGERPRINT: │ +│ • Geometry type (bracket, beam, mirror, shell, assembly) │ +│ • Number of design variables (1-5, 6-10, 11+) │ +│ • Objective physics (stress, frequency, displacement, WFE) │ +│ • Constraint types (upper/lower bounds, ratios) │ +│ • Solver type (SOL 101, 103, 105, 111, 112) │ +│ │ +│ LANDSCAPE METRICS (computed during characterization phase): │ +│ • Smoothness score (0-1): How continuous is the response? │ +│ • Multimodality: How many distinct good regions exist? │ +│ • Parameter correlations: Which variables matter most? │ +│ • Noise level: How much solver variation exists? │ +│ • Dimensionality impact: How does space grow with variables? │ +│ │ +│ PERFORMANCE OUTCOME: │ +│ • Trials to convergence │ +│ • Best objective achieved │ +│ • Constraint satisfaction rate │ +│ • Algorithm that won (if IMSO used) │ +│ │ └─────────────────────────────────────────────────────────────────┘ ``` -### How Protocol Routing Works +### Learning What Works: The LAC System -When a user says "create a new study", the AI: -1.
