A node list is a selection of nodes that define a specific area of the part. When investigating warpage, create a node list to define a section of the part you are interested in.
Deselect any results that are being displayed, and make sure that your nodes layer is selected in the Layers pane.
Click (View tab > Navigate panel > Select) to activate the Select Tool, and select all the nodes that define your area of interest.
Click (Mesh tab > Selection panel > Save Selection), type a name for your node list and click OK. Notice that all the nodes are listed in the Selection panel. The node list has been created and is now available for selection in the DOE Builder.
