Working with Geometric Entities
The topics in this section provide you with an introduction to the following:
About Geometric Entities defines the types of geometric entities in COMSOL, including information about adjacent and overlapping objects in the Graphics window.
The Graphics Window is the environment where the geometry is visualized and selected.
About Selecting Geometric Entities is an important section that helps you to understand how to highlight, select, or hide any part of the geometry using buttons, mouse clicks, keyboard shortcuts, or combinations of actions. Many physics feature node Settings windows have a common selection section, The Geometry Entity Selection Sections, which also has several useful buttons available on the Settings Window Toolbar.
The Selection List Window is a tool to help you to list all the specific geometric entities in the model and to locate and select, for example, small parts of complex geometries.
About Highlighted Geometric Entities in the Graphics Window describes the color scheme used to help you visually determine what geometric entities are included or excluded in a model. This makes it easy to add or remove domains, boundaries, edges, or points to the model. Also see
The section Selecting and Clearing Selection of Geometric Entities has a table with a list of the different ways to select geometry using a variety of windows, mouse buttons, clicks, and keyboard shortcuts.
The Graphics Window Toolbar Buttons and Navigation section includes a table with the different icons that display in the Model Builder (based on space dimension). The rest of the section describes the tasks related to the toolbar: Zooming In and Out in the Graphics Window, Changing Views in the Graphics Window, Moving Around and Rotating a 3D Geometry, Lighting, Transparency, Projection, and Wireframe Rendering, and Hiding and Showing Geometric Entities.
The section Using A 3D Mouse from 3Dconnexion describes how to activate and use a SpaceMouse® from 3Dconnexion®.
