### 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:
<node id="n">x,y,z</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>
