Help Resources: Installed and Web Versions

The technical content is available in HTML format as an Online Help system that you can access from two locations. Both versions are viewed in your browser.

  • A local version that is available with each Thermo-Calc installation and does not require an Internet connection.
  • A web version available online. The web help also matches the most recently released version of Thermo-Calc.

Between releases there may be minor updates to the web version compared to the installed version. All updates made to the web version are included in the next installed release version.

There are several resources available on our website to help you learn how to use Thermo‑Calc and other Add-on Modules. Go to the Getting Started Guides page and choose one of the guides that provides new users an introduction to setting up simple calculations in Graphical Mode. The information there is also in this help documentation.

See Welcome to Thermo-Calc to start navigating the help resources.

Opening the Web Version of the Help

  • A web version specific to each release version is available at https://help.thermocalc.com/2025b/content/intro/help-home.htm

Opening the Installed Help: No Internet Required

There are several ways to access online help in a browser. The content opens in a browser but uses local content so you do not need an Internet connection except for links to external websites.

First open Thermo‑Calc, then choose one of these options to go to the local browser version of the help:

  • Press <F1> on the keyboard.
  • Select Help → Help button Online Help.
  • On the My Project Configuration window, click Online Help button Start Page Online Help.
  • At the bottom of any Configuration window, click Help button Help.

Opening the Console Mode Help

Console Mode is for Thermo‑Calc and the Diffusion Module (DICTRA).

In Console Mode at the command line prompt, you can access help in these ways:

  • For a list of all the available commands in the current module, at the prompt type a question mark (?) and press <Enter>.
  • For a description of a specific command, type Help followed by the name of the command. You can only get online help about a command related to the current module you are in.
  • For general system information type Information. Specify the subject or type ? and the available subjects are listed. This subject list is specific to the current module.
