TUFLOW Message
WARNING 2934 - At least one merge polygon vertex is outside quadtree sub-domain. Current nesting level = n
Alternate Message
CHECK 2934 - At least one merge polygon vertex is located inside quadtree cell(s) from different nesting level. Processing nesting level = n
Description
Issues can occur in the TIN process when 2d_zsh polygons intersect with multiple quadtree levels.
Suggestions
Check by reviewing the _zsh_zpt and DEM_Z check files that the appropriate topography modifications have been applied. If they haven't, options include:
- extend the 2d_qnl to cover the entire 2d_zsh,
- create a TIN using QGIS or SMS and read the TIN into TUFLOW directly (using the TGC command 'Read TIN Zpts =='),
- snap 2d_zsh elevation points to every 2d_zsh polygon vertex, or
- use the "NO MERGE" option and supply elevations as needed.
