About CAEplex

CAEplex is a browser-based tool for thermo-mechanical finite element analysis. Users upload a CAD geometry, set up the problem and run it in the cloud, with no software to install and no dedicated hardware to maintain.

It comes from Seamplex, which develops free and open-source engineering software. CAEplex can also be added to Onshape through its app store.

What CAEplex offers

  • Mechanical elasticity — computes stresses in a part.
  • Heat conduction — thermal analysis of geometry.
  • Modal analysis — natural frequencies and shapes.
  • Cloud access — works from a browser, tablet or phone, with projects that can be shared.
  • Onshape add-on — a CAEplex tab inside a Part Studio.

Who it works with

Engineers who want simulation alongside their CAD work. Seamplex also publishes FeenoX and SunCAE, other open-source tools.

Key facts

  • Developer: Seamplex
  • Licence: free and open source
