### 3.6.4 Edge Section

The Edge section allows users to define a set of edges. These edges can be used to define boundary conditions or load.s
<Edge name="edge1">
<line2 lid="1">1,2</line2>
<line2 lid="2">2,3</line2>
</Edge>

Here, the lid attribute defines the local id of the edge, local with respect to the edge definition. The local ids must begin at 1 and defined sequentially.
The edge elements are defined by using a tag that depends on the type of the edge element. The following edge elements are currently supported.
line2 2-node line element
line3 3-node line element
