TUFLOW Message 2024
ERROR 2024 - Could not find a 1D node snapped to CN line.
Could not find a 1D node snapped to 2d_bc connection (CN) line.
Check snapping and location of 2d_bc "CN" type object. This should connect a 1D node to a 2D boundary condition, e.g. "HX" or "SX" type connection. The messages.mif or messages_P.shp file will contain the location of the error.
Check that the "CN" line finishes at a 1D node. In the example below, a single line has been digitised from the HX line to the HX line. Whilst it is snapped to the 1D node, it does not terminate there and therefore will cause Error 2024 to be generated.
Note that the direction the "CN" line is digitised is not important.
In the next image, this line has been split at the 1D node and the issue is resolved.
