TUFLOW FV
Available since version: 2026.2.0
WARNING 10241 - Very small angle encountered at cell <2d_cell_id>

Description

A very small interior angle was detected at a cell vertex during mesh preprocessing. Cells with very small interior angles indicate poor mesh quality and 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.
