The Application Libraries Window
To open an Acoustics Module application library model or tutorial, in the File menu click Application Libraries
. In the Application Libraries window that opens, expand the Acoustics Module folder and browse or search the contents.
Click Open Application
to open it in COMSOL Multiphysics or click Open PDF Document
to read background information including the step-by-step instructions to build it. The MPH files in the COMSOL application library can have three formats — solved, compact, or preview MPH files.
•
Solved MPH files, including all meshes and solutions. In the Application Libraries window these appear with the
icon. If the MPH file’s size exceeds 25MB, a tip with the text “Large file” and the file size appears when you position the cursor at the model’s node in the Application Libraries tree.
•
Compact MPH files with all settings for the model but without built meshes and solution data to save space (a few MPH files have no solutions for other reasons). You can open these to study the settings and to mesh and re-solve the applications. It is also possible to download the full versions — with meshes and solutions — of most of these when you update your application library. These appear in the Application Libraries window with the
icon and for runnable applications, this icon (
). If you position the cursor at a compact file in the Application Libraries window, a No solutions stored message appears. If a full MPH file is available for download, the corresponding node’s context menu includes a Download File with Solutions (
) option.
•
Preview MPH files (
) are not actual model MPH files. They just contain the information needed to present a model in the Application Libraries window. To get the actual model, choose Download File with Solutions (
) or Download File Without Solutions (
) from the node’s context menu.
To check all available Application Libraries updates, select Update COMSOL Application Library (
) either from the top of the Application Libraries window, from the File > Help menu (Windows users), or from the Help menu (Mac and Linux users).
To find further examples, available on the COMSOL homepage, click the Application Galley (
) button. The gallery contains all the library models and many more. It is a great location for finding resources on various acoustic topics.
