Attached Dimensions
An Attached Dimensions () node forms the Cartesian product of its selection in the base geometry and the entire geometries of all selected extra dimensions. It is possible to add several Attached Dimensions features forming Cartesian products with different sets of extra dimensions. Each such Cartesian product is called a product geometry.
Before Extra Dimensions can be used in physics, it must be attached on a selection in the base geometry. Under the base Component node, right-click Definitions and from the Extra Dimensions submenu, select Attached Dimensions.
Example: Solving Poisson’s Equation in a Cylinder by Means of Extra Dimensions
Geometric Entity Selection
From the Geometric entity level list, choose Entire geometry (the default), Domain, Boundary, Edge (3D), or Point to determine where extra dimensions should be attached.
Click the Active button to toggle between turning ON and OFF selections.
Attached Dimensions
In the Extra dimensions to attach list, add the Extra Dimension features to attach. A product geometry is formed as the Cartesian product of the selection of geometric entities in the base geometry and the entire geometry in all selected extra dimensions. Use the Move Up (), Move Down (), Delete (), and Add () buttons to make the list contain the Extra Dimension features that you want to attach. See Figure 16-4.
When the Attached Dimensions () node is used in the Extra dimensions to attach by some selection in the model, it is not possible to make changes in the list of attached dimensions.
To make a change in the list of attached dimensions, change the Extra dimensions to attach list in all selections using the Attached Dimensions feature to some other Attached Dimensions feature or to None.
Deleting an Attached Dimensions node from the model resets Extra dimensions to attach to None for all selections using this Attached Dimension node.
Figure 16-4: The Attached Dimension feature lists all the Extra Dimensions added to a Component. In this example, there are 3D and 2D Extra Dimensions at the Global level. Note that there is also a Definitions node under Extra Dimensions that contains a default Points to Attach feature.
