TUFLOW Message
ERROR 2467 - Overlapping Layered Flow Constriction Shape at ZV point.
Alternate Message
ERROR 2467 - Overlapping Layered Flow Constriction Shape at ZU point.
CHECK 2467 - Layered Flow Constriction Shape overlaps with Flow Constriction Shape at ZV point.
CHECK 2467 - Layered Flow Constriction Shape overlaps with Flow Constriction Shape at ZU point.
Description
A cell side encountered overlapping flow constrictions.
Suggestions
From the 2023 release, overlapping Layered Flow Constriction Shapes and 2D Bridge Shapes trigger ERROR 2467.
In earlier releases, overlapping Layered Flow Constriction Shapes could be processed at the same cell side during the form loss calculation. For TUFLOW Classic, the last read Layered Flow Constriction Shape was used. For TUFLOW HPC, the order in which overlapping shapes were processed could not be determined due to GPU parallel processing, meaning it was not possible to reliably confirm which value was applied in the hydraulic calculation.
Modify the flow constriction inputs so that they do not overlap at the same 2D cell side. If the overlap is intentional, combine the required parameters into a single appropriate flow constriction rather than using overlapping inputs.
After making the changes, review the relevant check files to confirm that the intended cell sides and form loss values are being applied.
