Line 44:
* In regions of low velocity (<0.5m/s), the “d” value should be no less than three times the distance of the larger cell resolution associated with the 2D/2D boundary. For example, if the model adopts a 2.5m and 5m resolution, the “d” attribute should be set no smaller than 15m.<br>
* In regions of moderate to high velocity (>0.5m/s),larger or no “d” value is common used. Not specifying a “d” value will create a hidden 1D node at each vertex along the 2d_bc “2D” link line.<br>▼
