No need to install any extra software

Just open a regular web browser such as Firefox or Chrome and search online for “caeplex.” It works in any operating system such as Windows, MacOS, GNU/Linux, iOS, Android, etc.


No need to buy extra hardware

The computations are performed on our servers so CAEplex works on any existing PC, laptop, tablet or phone without requiring any hardware update nor maintenance. No need to buy a new computer nor to add RAM to your oldie one.

Quick & easy

Get results in seconds (literally)

Our killer feature: “ease and speed.” A CAEplex case can be solved from scratch down to the results in less than one minute thanks to our 3-step workflow. If you know a faster FEA app, please let us know.


Use it from a tablet or smartphone

CAEplex can be used from any mobile device such as a tablet or phones, no matter how old or wrecked. Access and show your work from any location at any time.

CAEplex’ features

The 3-step workflow

1. Problem

Define material properties and boundary conditions
