Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@ettaouly/mechatronics-cad-engine ⚙️⚡

Open-source High-Precision Mechatronics, FEA Stress Computation & DFM Optimization Engine
Engineered by Asma Ettaouly (Productics & Mechatronics Specialist) & Abdelali Ettaouly (Full-Stack & Systems Architect).

🌟 Overview

@ettaouly/mechatronics-cad-engine provides specialized mathematical algorithms for finite element analysis (FEA), von Mises stress verification, plastic injection DFM wall-thickness checking, and 3D GD&T tolerance stack-up analysis according to ISO 1101 and ASME Y14.5 standards.

Official Bureau d'Études Platform: https://ettaoulyengineering.com

🚀 Features

  • FEA von Mises Stress Calculator: Evaluate structural integrity and safety factors ($s \ge 2.5$) for aerospace and EV components.
  • DFM Wall-Thickness Inspector: Detect sinks, warpage risk, and weld lines for plastic injection molding (Moldflow integration).
  • GD&T Tolerance Stack-Up (Worst-Case & RSS): Calculate clearance bounds for 3D assemblies under manufacturing variations.
  • Topological Weight Reduction Engine: Compute bionic material removal percentages for additive manufacturing (SLM Titanium / SLS PA12).

📦 Installation

npm install @ettaouly/mechatronics-cad-engine
# or
yarn add @ettaouly/mechatronics-cad-engine

💡 Usage Example

import { computeVonMisesStress, checkDFMWallThickness, calculateWorstCaseTolerance } from '@ettaouly/mechatronics-cad-engine';

// 1. Compute von Mises stress for a load-bearing bracket
const stressResult = computeVonMisesStress({
  sigmaX: 120, // MPa
  sigmaY: 45,  // MPa
  tauXY: 30,   // MPa
  yieldStrength: 310 // MPa (Aluminium 7075-T6)
});

console.log(`Von Mises Stress: ${stressResult.vonMises} MPa`);
console.log(`Safety Factor: ${stressResult.safetyFactor} (Status: ${stressResult.isSafe ? 'SAFE' : 'REJECT'})`);

// 2. DFM Wall-Thickness Validation
const dfmCheck = checkDFMWallThickness({
  nominalThickness: 2.5, // mm
  minRecommended: 1.5,
  maxRecommended: 4.0
});

console.log(`DFM Pass: ${dfmCheck.valid}`);
