3.6.1 Nodes Section
The Nodes section contains nodal coordinates. It has an optional attribute called name. If this attribute is defined, the Nodes section also defines a node set.
<Nodes [name="<set name>"]>
The nodes are defined using the node tag which is a child of the Nodes section. Repeat the following XML-element for each node:
The id attribute is the global identifier of the node and must be a unique number within the model definition. This id is used as a reference in the element connectivity section.
Multiple Nodes sections can be defined, but each node can only be defined once. For example:
<Nodes name="set01"> <node id="1">0,0,0</node> ... <node id="101">1,1,1</node> </Nodes> <Nodes name ="set02"> <node id="102">2,1,1</node> ... <node id="999">2,2,2</node> </Nodes>
