The Model Selection dialog is used to select models and to change the model selection in a simulation. To activate the dialog in a continuum (say Continuum 1), open the Continua node and right-click on the Continuum 1 node. In the pop-up menu select the item Select models...

This same menu item is available in the pop-up menu of the Models manager node under the continuum node.
Model selection and deletion can only be done through this dialog:
In this and the following sections, the descriptions and illustrations of model selection refer to physics models; however, the general principles apply to meshing models as well. The screenshot below shows the dialog part way through a selection process, where each significant aspect of the dialog can be seen.
