定义 / Coordinate-Based Selection

Maintain model setup despite geometry changes.

When setting up models, it is often helpful to use selections to represent various parts of your geometry. These selections can then be utilized for all of the steps in creating your simulation, such as specifying materials and applying boundary conditions.

In the COMSOL Multiphysics® software, you can use coordinate-based selections, which include the Ball Selection, Box Selection, and Cylinder Selection, to create selections that are partially or completely enclosed by any of the aforementioned shapes. These selection types also automatically update if the geometry in your model changes.

In this video, we show you how to use these selection tools in your simulations and review the advantages of doing so. We encourage you to follow along with us by downloading the exercise files for this video.
