The Xubuntu 18.04 LTS based CAELinux 2020 is released with major improvements with more customizations and pre-loaded tools, utilities. CAELinux is a distribution aimed to help in simulating various engineering areas by pre-loading free and open-source simulation tools.

CAELinux 2020 comes with tools for stress analysis, thermal and fluid flow simulations, mathematical modeling tools, graphic and design software, CAD/CAM, prototyping software which makes it ideal for running a fabrication software.

The core of CALinux 2020 is Xubuntu 18.04 LTS with the XFCE desktop environment and can run directly from USB without installation.

CAELinux 2020 Updates

  • One of the major updates on this release is the resolution of the .iso installer size problem.
