Busbar Assembly Geometry — with Group Nodes
Introduction
Group nodes in the Model Tree can help with the organization of models by grouping feature nodes that belong together, for example, nodes that belong to a particular part of the geometry, in a folder-like structure.
You can collapse group nodes, drag the group nodes to rearrange them, or drag other nodes to or from the group nodes. Actions like hiding can be applied to all members of a group node, making it more efficient to work with more complex geometries.
Follow this tutorial to create the busbar geometry used in the model Electrical Heating in a Busbar Assembly while learning more about how to:
•
Collect geometry feature nodes into group nodes
•
Set up work planes with user defined local coordinate systems
•
Position geometry objects in various ways
Busbar Assembly Geometry — with Geometry Parts, the first part of this tutorial series, describes how to built a geometry that consists of several components by using geometry parts. The two tutorials in this series complement each other, and show methods to structure more complex geometry sequences.
Model Definition
This example contains the detailed steps to create the parameterized geometry used for the model Electrical Heating in a Busbar Assembly. The geometry for this model, displayed in Figure 1, includes the coupling components for one cell, and a section of the intercell busbar that is connected to a cell grid.
Figure 1: The busbar assembly.
When creating the geometry, you will collect feature nodes that build the components of the busbar into separate group nodes. Another approach to organize the geometry sequence could be to group the feature nodes based on, for example, the material properties.
This example describes only the process of creating the geometry sequence. For the physics setup, follow the instructions in Electrical Heating in a Busbar Assembly.
