Settings

In openLCA, settings concerning connection, language, or parameters are summarised in a separate section „Preferences”.

Connection settings

You can change your connection and set default connection. Go to „File” and click on „Preferences”.

Now a new window will appear:

Click on „Connection settings” and select your connection in the right section. Finally confirm your choice by clicking „Apply” or „OK”. If you want to undo your changes click on „Restore Defaults”.

Language settings

If you want to change the language, go to „File” and click on „Preferences” (see above).
Then select „Language settings” in the window and change the language by clicking on the arrow and click on „OK”. Please note that you have to restart openLCA to make the changes valid. If you want to undo your changes click on „Restore Defaults”.

Parameter settings

Also regarding parameters you can make several settings in the menu.

Creating global parameters

Go to „File”, click on „Preferences” and go to the menu item „Global Parameters” under „Parameter settings”.

Click on the green plus symbol to add a new global parameter. Fill in a name, enter a formula or a value for the parameter (for input rules click here), and describe the parameter (optional). If you mark a parameter and click on the red cross you can delete it. Finally click on „Apply” or „OK” to save the changes.

Determining the parameter hierarchy

If you define global and local parameters you have to determine a parameter hierarchy. Either you choose a top down direction (global parameters will overwrite local ones) or you choose a bottom up direction (local parameters will overwrite global ones). To do this go to „File”, click on „Preferences”, and click on „Parameter settings”. Here you can select a direction. Finally click on „Apply” or „OK” to save the changes.
