TUFLOW Message 1041

TUFLOW Message
ERROR 1041 - Culvert branch splits downstream of channel ",a," at Node ",a,". Could not interpolate invert.

Alternate Message
ERROR 1041 - Culvert branch splits upstream of channel ",a," at Node ",a,". Could not interpolate invert.

Message Type
ERROR

Description
Multiple upstream or downstream channel, unable to interpolate inverts.

Suggestions
A useful tip at a junction of 1D channels is to use a connector (Channel_Type of “X”) for connecting a side tributary or pipe into the main flowpath. TUFLOW will then be able to interpolate inverts.
Specify inverts upstream and downstream of the culvert, either via the US_invert / DS_invert in the 1D channel object or via snapped 1D node objects.
