TUFLOW Message 3022

TUFLOW Message
ERROR 3022: Number of Boundary Level Graphs exceeded. Maximum is 253.

Alternate Message
None

Message Type
ERROR

Description
TUFLOW HPC has a limit of 253 unique H (HS and HT) boundaries.

Suggestions

• Check total number of HS and HT boundaries in the 2d_bc layer is more than 253.
• Check number of HS and HT boundaries read in the model by searching for "nhs" and "nht" in the .tlf file. If the number is higher than the number of HS and HT boundaries in the 2d_bc layer then check if attributes "td", "a" and/or "b" have any (non-zero) values specified. These attributes adjust the boundary values incrementally along each cell of the HS/HT boundary, thereby creating a unique boundary time-series for each cell and can significantly increase the number of unique boundaries.
