The Application Libraries Window
The Application Libraries window (Figure 2-12) contains sets of models and applications that you can use for a variety of purposes: for learning how to build COMSOL models, as starting points for your own models and applications, and as demonstrations of specific functionality. Each add-on module includes its own application library with information about how to use the module within its application areas. Each file includes full documentation and a brief description, including the solution times and information about the computer used for solving the model.
Figure 2-12: The Application Libraries window with Eigenmodes of a Room highlighted in the tree. Specific information about the model or application is displayed to the right, including its name and the computation time.
Browse through the Application Libraries tree to see what is available for your license. Click to highlight the file in the tree and read the information about it to the right, or search for a specific application. The information for each application includes:
•
The COMSOL products used.
•
The physics interfaces used.
•
The version that the application was created in.
•
The computation time. If you hover over the computation time, a tooltip displays information about the computer used for the computation (CPU, clock rate, and number of cores) and, if applicable, the solution times for each study step.
•
The dates and times for when the application was created and last modified.
 
To open the Application Libraries window ():
•
From the Home toolbar, Windows menu, select Application Libraries.
•
You can also customize the Quick Access Toolbar and then click the Application Libraries button on the toolbar. See Windows Toolbars and Menus.
•
From the File menu select Application Libraries.
To open the Application Libraries window ():
•
In the Main toolbar, click the Application Libraries button.
•
Select Windows>Application Libraries.
The following sections describe what is available and what you can do from the Application Libraries window:
•
The Applications Folders
•
Running or Opening a Model or Application and Its Documentation
•
Downloading MPH-Files With Solutions
•
Searching the Application Libraries
•
The Application Library Update Window
You can also set the root directory and create and remove a user-defined library as described next.
Application Library Preferences
The following settings can be modified using the buttons at the bottom of the Application Libraries tree on the Application Libraries page in The Preferences Dialog Box and — if the Allow managing libraries in the Application Libraries window check box on that page is selected (the default) — also in the Application Libraries window itself.
Add User Application Library
Click the Add User Application Library button () to add customized folders. In the Add User Application Library dialog box, navigate to a location on your computer and select an existing directory or click Make New Folder to create a custom folder. Click OK to save the changes and exit, or Cancel to exit without saving.
It is not possible to add an application library identical to, containing, or being contained in, an already used application library.
Optionally, you can replace the standard folder icon () with custom icons of your choice that reflect the content of your library folders. To use a custom icon for a folder, create a PNG-file with an image size of 16-by-16 pixels and save it in the folder under the name folder.png.
Set the COMSOL Application Libraries Root
Click the Set COMSOL Application Libraries Root Directory button () to edit or set the root folder. This redirects the COMSOL software to a different folder where customized applications can be stored.
In the Set COMSOL Application Libraries Root Directory dialog box, navigate to the new root folder location or click Make New Folder. Click OK to save the changes and exit, or Cancel to exit without saving.
Remove Selected Library
This button is enabled after a user application library folder has been created. Select a user application library root folder in the Application libraries tree and then the click the Remove Selected () button to remove the library from the tree.
