Meshing Operations and Attributes
After a Mesh has been added to the Component node, the Mesh ribbon toolbar (Windows) or the Mesh contextual toolbar (macOS and Linux) is made accessible. Click a meshing sequence node in the Model Builder and the Mesh tab or toolbar displays on the COMSOL Desktop.
In general, the instructions throughout the documentation indicate that you click a button on a Mesh toolbar, no matter what operating system you are running.
Figure 8-4: Click a Mesh node or any node under the Mesh node (Free Tetrahedral, for example) to open the Mesh ribbon toolbar (Windows users, top) or Mesh contextual toolbar (macOS and Linux users, bottom). Only some of the available buttons are shown in this image.
Click the associated menu arrow and choose the menu item corresponding to the mesh node. If you click the button associated with this menu button COMSOL Multiphysics selects the node in the Model Builder corresponding to the last selected item in the menu associated with the menu button.
Predefined Mesh Element Sizes
The following table shows the icons on the drop-down menus for selecting predefined mesh element sizes:

Geometric Measurements
To measure the volume, area, or length of a selected domain, face, or edge, respectively, click the Measure button (). The result displays in The Messages Window. Using this button it is also possible to view the coordinates of a vertex, the distance between two vertices, or the number of entities and the geometry representation (only if you have license for the CAD Import Module) of a geometry object.
The Mesh Toolbar in 1D and 2D contains a subset of the tools in the 3D toolbar.
