User Interface / Selecting Geometry

Select hard-to-reach geometric entities. Duration: 10:41

When setting up a simulation, there are many instances in which you will need to select geometric entities, such as domains or boundaries, in your model. The COMSOL Multiphysics^® software contains many functionalities for selecting geometric entities in your model that make working with complex geometries or reaching interior domains and boundaries easy.

This video explains each method and its advantages in different scenarios, including using:

The mouse in the Graphics window to select simple geometries or individual entities
The mouse scroll-wheel button to reach interior geometric entities
The Graphics window toolbar to select multiple entities quickly
The Selection List window to use for complex geometries
The Settings window toolbar to copy and paste lists of geometric entities from one node's settings to another
Preselections to add physics nodes from the ribbon
