Under the Global Definitions node (), the following branches and nodes contain functionality that is global and applies to the entire model:
• Right-click the Global Definitions node to add global parameters, variables, user-defined functions, and load and constrain groups. See Global Definitions.
• The Geometry Parts branch (), where you can add and link geometry parts for use with the model geometries. This branch is not visible by default. To add it, right-click the Global Definitions node and choose Geometry Parts. See Global Geometry Parts.
• The Mesh Parts branch (), where you can add and link mesh parts for use with the model geometries. This branch is not visible by default. To add it, right-click the Global Definitions node and choose Mesh Parts. See Global Mesh Parts.
• The Materials branch (), where you can define materials with material properties that you can use for defining material properties throughout the model. See Global Materials.
• Optionally, you can add Extra Dimension nodes that represent extra, abstract spatial dimensions. See Adding Extra Dimensions to a Model.
