Where Do I Access the Documentation and Application Libraries?
A number of online resources have more information about COMSOL, including licensing and technical information. The electronic documentation, topic-based (or context-based) help, and the Application Libraries are all accessed through the COMSOL Desktop.
If you are reading the documentation as a PDF file on your computer, the blue links do not work to open an application or content referenced in a different guide. However, if you are using the Help system in COMSOL Multiphysics, these links work to open other modules, application examples, and documentation sets.
The Documentation and Online Help
The COMSOL Multiphysics Reference Manual describes the core physics interfaces and functionality included with the COMSOL Multiphysics license. This book also has instructions on how to use COMSOL Multiphysics and how to access the electronic Documentation and Help content.
Opening Topic-Based Help
The Help window is useful as it is connected to the features in the COMSOL Desktop. To learn more about a node in the Model Builder, or a window on the Desktop, click to highlight a node or window, then press F1 to open the Help window, which then displays information about that feature (or click a node in the Model Builder followed by the Help button (). This is called topic-based (or context) help.
To open the Help window:
•
In the Model Builder, Application Builder, or Physics Builder, click a node or window and then press F1.
•
On any toolbar (for example, Home, Definitions, or Geometry), hover the mouse over a button (for example, Add Physics or Build All) and then press F1.
•
From the File menu, click Help ().
•
In the upper-right corner of the COMSOL Desktop, click the Help () button.
To open the Help window:
•
In the Model Builder or Physics Builder, click a node or window and then press F1.
•
In the main toolbar, click the Help () button.
•
From the main menu, select Help>Help.
Opening the Documentation Window
To open the Documentation window:
•
Press Ctrl+F1.
•
In the main toolbar, click the Documentation () button.
•
From the main menu, select Help>Documentation.
The Application Libraries Window
Each model or application includes documentation with the theoretical background and step-by-step instructions to create a model or application. The models and applications are available in COMSOL Multiphysics as MPH-files that you can open for further investigation. You can use the step-by-step instructions and the actual models as templates for your own modeling. In most models, SI units are used to describe the relevant properties, parameters, and dimensions, but other unit systems are available.
Once the Application Libraries window is opened, you can search by name or browse under a module folder name. Click to view a summary of the model or application and its properties, including options to open it or its associated PDF document.
Opening the Application Libraries Window
