The software installation runs automatically.

Installed components

The automatic installation installs the following components:
  • The Altair Flux Version 2026 software
  • The Altair Flux Version 2026 documentation and examples:
    • the documentation in English version: installation guide and user guide,
    • the documentation in French version: user guide,
    • the examples: tutorials and technical papers (in English version only), with the corresponding Flux projects and/or command files.

Installation directories

  • by default:
    • with an unprivileged account: in the directory /home/<username>/2026
    • with the root account: in the directory /root/2026
  • or in any other directory specified by the user during the installation.
    Warning: The full installation directory path must not include any special characters.
