Selection (Dataset Attribute)
For datasets that contain data defined in the model, such as Solution datasets () and Mesh datasets (), you can add a selection so that the results and plots use a subset of the geometry. As an alternative, you can add Selection subnodes to some of the plot nodes; see Selection (Plot Attribute).
To add a Selection subnode to a dataset:
In the Results toolbar, click Attributes>Selection ().
Under Results>Datasets, right-click a dataset and choose Selection ().
In the Selection subnode (), select the geometric entities for which you want to include data in the dataset using the Graphics window and the settings under Geometric Entity Selection in the Selection subnode’s Settings window. Select the Propagate to lower dimensions check box to make a selection of domains, for example, also include their adjacent boundaries, edges, and points. This can be convenient when using Surface plots on the boundaries of a 3D geometry, for example.
