TUFLOW FV
Available since version: 2026.2.0
Description
A very large interior angle was detected at a cell vertex during mesh preprocessing. Cells with interior angles approaching 180° have nearly collinear consecutive vertices and indicate poor mesh quality. This can affect numerical accuracy, stability and speed during the simulation.
Suggestions
Review the mesh in the vicinity of the flagged cell. The GIS messages output file shows the location of the problematic vertex which can be used to identify the area requiring attention. Regenerate the mesh with improved element quality.
