Since our start in 1994, IES engineers have helped thousands of people, just like you, with innovative structural analysis and design tools. We are experienced engineers with advanced degrees and a passion for software development.
When we started, engineering software was a black-box tool that required you to write scripts in arcane formats and interpret tables of numbers. Our goal is to create reliable tools that are engineer friendly.
We deliver products that speak your language, display your work graphically, prevent errors, and help you succeed. We validate our tools to provide you with the highest quality software. We strive to make the best FEA software available.
Our programs help you solve very complex problems with confidence while streamlining day-to-day jobs so you meet your deadlines.
