'''<u>2D BC "2D" Line Vertex Location and Hidden 1D Node Options'''</u>'''<br>
As previously mentioned, flow is transferred between both domains via a series of hidden 1D nodes. TUFLOW creates these at each vertex along the 2d_bc "2D" link line and also at a regular interval, as defined by the “d” attribute
2d_bc “2D” link line vertices are best located on ridges or embankments, including features that become inundated and drowned out during a simulation.<br>
* In regions of moderate to high velocity (>0.5m/s), manual vertex placement on the river banks and natural ridges in addition to a “d” value of 0 is common. Using a “d” value of 0 will create a hidden 1D node at each vertex along the 2d_bc “2D” link line.<br>▼
