Learning to Use General-Purpose, Time-Saving Features

---

In COMSOL Multiphysics^®, there are many features and functionality that enable you to more quickly perform actions or tasks in the software, customize aspects of the user interface like buttons in toolbars, and generally expedite the model building process. In this article, we introduce you to some of these features of the user interface.

Using theGo to SourceButton

One option to move around in the model tree is to use theGo to Sourcebutton. This button appears next to lists where you can select, for example:

• The dataset to use in a plot group
• The solution to use in a dataset
• The study step that defines the settings for a solver
• A common model input used as the value for a material property in a physics interface

Clicking theGo to Sourcebutton moves the focus from the node with that button to the node that contains the source selected in the list that theGo to Sourcebutton belongs to. For example, as shown in the following images, when you click theGo to Sourcebutton next to theDatasetlist in theSettingswindow for theStress (solid)plot group, the focus moves to theStudy 1/Solution1 (1)dataset node underDatasetsabove the plot group in the model tree.

When you click theGo to Source button for the dataset, the focus moves to theStudy 1/Solution 1 (1) dataset, which is the data source for the plot.

TheQuick AccessToolbar

The Quick Access Toolbar appears at the very top of the COMSOL Desktop^®and contains a customizable set of buttons for common operations, such asNew,Open,Save,Undo,Redo,Copy,Paste,and more. As of COMSOL Multiphysics^®version 6.0, there are options available for the Model Manager to switch between workspaces and for refreshing add-ins. To customize the set of buttons on the Quick Access Toolbar, click the down arrow to the right of the toolbar to open theCustomize Quick Access Toolbarmenu. You can then right-click the Quick Access Toolbar; chooseShow Quick Access Toolbar Below the Ribbon, for example, from a set of standard buttons; and add more commands.

When you chooseMore Commands, theQuick Access Toolbardialog box appears. In the dialog box, you can choose commands to add or remove from the Quick Access Toolbar using theAdd>>and<buttons, respectively. When you select a command button in the set of active commands to the right, you can use the up and down arrow keys to change the order of the buttons.

Although most of the buttons in the Quick Access Toolbar have predefined keyboard shortcuts, such as Ctrl+S forSaveor Ctrl+Z forUndo, you can also activate numerical keyboard shortcuts for the Quick Access Toolbar. To do so, press the Alt key. Numbers representing each button then appear (see the following image). Press the corresponding number keys to activate the command for that button.

Press the Alt key to display the keyboard shortcuts for theQuick Access Toolbar.Then, for example, press 2 to open a new model file.

Double-Clicking to Quickly Add Features

In many situations where you are adding something to a model, such as a physics interface, study, or material, simply double-click the item that you want to add. It is then added directly to the model tree without the need to click theAdd to Componentbutton, for example. In the Model Wizard, double-clicking a physics interface on theSelect Physicspage adds it to the list underAdded physics interfaceswithout the need to click theAddbutton. On theSelect Studypage, double-clicking a study adds it underAdded studyand exits the Model Wizard without the need to click theDonebutton.

Preference for Unit System in New Models

If you often use a unit system other than SI, you can alter theIn new modelspreference in thePreferencesdialog box so that new models always use the unit system you choose.

Compact Save

For large models, saving the computed data with the model takes up a lot of storage space. Options are available as of COMSOL Multiphysics^®version 6.0 that prevent built, computed, and plotted data from being saved but retain the data in the current session as long as the model remains open. There are also separate options for when you are storing the model as an MPH-file, and when you are storing it in a database using the new Model Manager.
