Linux Installation Notes

The following are details you need to know regarding your Linux installation as well as how to open Thermo‑Calc.

openSUSE Administration (sudo) Users

Note the following if you are a sudo user (administrator) in openSUSE installing Thermo‑Calc using this command:

sudo ./Thermo-Calc-linux-<full-version-number>.run

When this command is used, you will do a text-based installation instead of having a graphical interface to guide you. The information is the same, just without the user interface.

For example, the <full-version-number> is not just 2025b, it is what is found in the Help → About window in Thermo-Calc and it changes every release. You can find the current full version number listed on our website.

Opening Thermo‑Calc in Linux

To open Thermo‑Calc double-click the Thermo‑Calc-2025b application or from the Thermo‑Calc installation directory enter $ ./Thermo‑Calc-2025b.sh in the terminal.
