TUFLOW Message
ERROR 2042 - Cannot find upstream ISIS unit node for 2D HX cell.

Alternate Message
NA

Message Type
ERROR

Description
Cannot find or identify upstream ISIS unit node for 2D HX cell.

Suggestions
Check for ISIS nodes that have been digitised within a 1d_x1d_nodes GIS layer that are not snapped to CN lines. For example, the figure below shows node FC01.25a does not have any associated CN connection lines digitised within a 2d_bc layer. Digitise the CN lines to connect the ISIS node to the 2D floodplain.
