When setting up a model, it can be a cumbersome task to keep track of the settings that are applied to the geometry. This is especially the case for complex simulations, such as those involving multiple physical phenomena. Explicit selections in COMSOL Multiphysics® can be utilized to create selections of individual geometric entities. This helps simplify your model and streamline your workflow. In this video, we show you how to create Explicit selections and review the available options, as well as discuss the advantages and limitations of using this selection tool.
