Toolbar: File

The following options are available under File:

  • Save / Save As... / Save All: This option saves the work that is currently opened in the editor tabs. Unsaved tabs will be not included in the calculations that will be performed.

  • Close / Close All: This option closes the current/all windows opened in the editor.

  • Preferences: Under preferences, you can customize openLCA upon your needs. Here, you can find settings as memory allocation for openLCA, and language selection.

    • Collaboration: Here, you can select your preferred configurations for working with the collaboration server.

      • Check referenced changes: if this is checked, openLCA will scan - after selecting datasets for a commit - the database for changes in datasets that are referenced by the selected datasets and suggests to also commit them. E.g. if you want to commit a process dataset, and you have added a newly created flow to the input table, the flow is considered a referenced change.

      • Enable comments: if this is checked, openLCA loads comments that were added to data sets on the LCA Collaboration Server and displays them in the model editors.


        Preferences Collaboration

      More information about the Collaboration Server can be found in the respective chapter.

    • Configuration: Here you can choose among eleven available languages (Arabic, Bulgarian, Catalan, Chinese, English, French, German, Italian, Portuguese, Spanish or Turkish). You can also select the maximum memory usage (see chapter).

      Preferences Configuration

      • Graphical editor theme: You can change now the theme for the model graph and Sankey diagram namely: Dark, Light, Nord Dark, Nord Light, Poimandres. However, to access the dark mode for the whole application, you need to select it on your operating system.

      • Reset window layout: Furthermore, you can reset your window settings if you encounter a bug or if you find yourself lost with the number of open windows.

      • Download calculation libraries: This option allows you to integrate fast calculation libraries for openLCA. This function is still developed currently.

      Note: You need to restart openLCA to activate configuration changes.

    • Experimental features: These features are still in development, but you can already access them by checking this box. We welcome any feedback to further refine them. Here you can activate the novel social impact assessment feature.


      Preferences Experimental Features

    • Import/Export: Here you can change the ILCD Network settings (currently under development).

    • Logging: Here you can set what information should be written in openLCA's log file. You can also keep the log file opened permanently if you want.

    • Number format: If you are not a fan of the six-decimal display format, you can modify it here. This setting will not affect calculation results and it is just for your convenience, adjusting the format in the user interface.

    In case you made a mistake here, "Restore Defaults" will always bring you back to the default settings.

  • Import: See section "Importing and combining databases"

  • Export: See section "Exporting data"

  • Exit: This option closes openLCA, as well as clicking on the small cross at the right corner of openLCA.
