Neural Acceleration (MLP Surrogate): - Add run_nn_optimization.py with hybrid FEA/NN workflow - MLP architecture: 4-layer (64->128->128->64) with BatchNorm/Dropout - Three workflow modes: - --all: Sequential export->train->optimize->validate - --hybrid-loop: Iterative Train->NN->Validate->Retrain cycle - --turbo: Aggressive single-best validation (RECOMMENDED) - Turbo mode: 5000 NN trials + 50 FEA validations in ~12 minutes - Separate nn_study.db to avoid overloading dashboard Performance Results (bracket_pareto_3obj study): - NN prediction errors: mass 1-5%, stress 1-4%, stiffness 5-15% - Found minimum mass designs at boundary (angle~30deg, thick~30mm) - 100x speedup vs pure FEA exploration Protocol Operating System: - Add .claude/skills/ with Bootstrap, Cheatsheet, Context Loader - Add docs/protocols/ with operations (OP_01-06) and system (SYS_10-14) - Update SYS_14_NEURAL_ACCELERATION.md with MLP Turbo Mode docs NX Automation: - Add optimization_engine/hooks/ for NX CAD/CAE automation - Add study_wizard.py for guided study creation - Fix FEM mesh update: load idealized part before UpdateFemodel() New Study: - bracket_pareto_3obj: 3-objective Pareto (mass, stress, stiffness) - 167 FEA trials + 5000 NN trials completed - Demonstrates full hybrid workflow 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Atomizer NX Open Hooks
|
|
======================
|
|
|
|
Direct Python hooks for NX CAD/CAE operations via NX Open API.
|
|
|
|
This module provides a clean Python interface for manipulating NX parts
|
|
programmatically. Each hook executes NX journals via `run_journal.exe`
|
|
and returns structured JSON results.
|
|
|
|
Modules
|
|
-------
|
|
nx_cad : CAD manipulation hooks
|
|
- part_manager : Open, close, save parts
|
|
- expression_manager : Get/set design parameters
|
|
- geometry_query : Mass properties, bodies, volumes
|
|
- feature_manager : Suppress/unsuppress features
|
|
|
|
nx_cae : CAE/Simulation hooks (Phase 2)
|
|
- solver_manager : BDF export, solve simulations
|
|
|
|
Quick Start
|
|
-----------
|
|
>>> from optimization_engine.hooks.nx_cad import expression_manager
|
|
>>> result = expression_manager.get_expressions("C:/model.prt")
|
|
>>> if result["success"]:
|
|
... for name, expr in result["data"]["expressions"].items():
|
|
... print(f"{name} = {expr['value']}")
|
|
|
|
>>> from optimization_engine.hooks.nx_cae import solver_manager
|
|
>>> result = solver_manager.get_bdf_from_solution_folder("C:/model.sim")
|
|
|
|
Requirements
|
|
------------
|
|
- Siemens NX 2506+ installed
|
|
- NX_BIN_PATH environment variable (or default path)
|
|
- Python 3.8+ with atomizer conda environment
|
|
|
