TUFLOW Message 2833
TUFLOW Message
ERROR 2833 - Exceeded limit of "<>" mesh boundary polygons.
Alternate Message
WARNING 2833 - Exceeded limit of "<>" polygon internal regions - trying to write simplified polygon.
Description
ERROR 2833 - This error can occur in Quadtree during the domain calculation where TUFLOW will create a polygon of the active mesh area. If there are a number of inactive areas in the domain, then these are stored as polygons (or "rings" in GIS geometry terminology). The error is triggered if the number of rings has unexpectedly exceeded the allowed memory. This is most likely an internal logic error within TUFLOW (similar to a "should not be here").
WARNING 2833 - The number of internal polygons (or "rings") has exceed the allowed number within TUFLOW. This is a hard coded value in TUFLOW.
Suggestions
ERROR 2833 - Since this most likely an internal logic error within TUFLOW, you will need to contact support@tuflow.com. Workarounds include double checking the Quadtree mesh for "messy" holes around nesting transition zones. Moving transition areas away from deactivated areas may fix the logic error.
WARNING 2833 - Most likely the only workaround is to remove the number of inactive areas in the Quadtree mesh. These are typically caused by building footprints being used to deactivate areas within the mesh. Simplifying, or grouping buildings together will reduce the number of total holes in the domain polygon.
