Element
An Element node creates a new element of the type entered in the Element type field. This node is a special type of Record node that represents the top level of an element.
In addition to the type entered in the Element type field, selecting the Auxiliary element check box enables the use of a special family of elements called auxiliary elements. These are used to define solver events, which the Event node also creates.
To add this node, go to Building Blocks. Right-click Components to add a Component node. Then select Element from the Elements menu.
