Product Updates and Application Library Update
COMSOL periodically releases product updates with improvements and corrections to reported problems. By default, COMSOL checks for updates at startup. You can turn this feature on and off from the COMSOL Desktop Preferences window. Here you can also configure settings for the Application Library Update.
The COMSOL Application Library is updated on a regular basis by COMSOL. To open the Application Library Update window from the File>Help menu (Windows users) or from the Help menu (Mac and Linux users), select Update COMSOL Application Library.
This connects you to the COMSOL Application Update website where you can access the latest updates. This includes applications that have been added or improved since the latest product release.
Using the Updates section in the Preferences dialog box, which you open from the COMSOL Desktop, you can configure proxy server settings as well as application and documentation directories for the Application Library Update. See the COMSOL Multiphysics Reference Manual for more information including command-line options for the Application Libraries.
