TUFLOW FV

Available since version: 2026.2.0

WARNING 10117 - Cartesian model specified with coordinates within range [-360.,360.], [-90.,90.]. Check if spherical coordinates should be specified.

Description

The model is set to use a Cartesian coordinate system, but all mesh node coordinates fall within the range typical of geographic (longitude/latitude) coordinates (x within ±360°, y within ±90°). This may indicate that the coordinate system setting in the control file does not match the coordinate system of the mesh.

Suggestions

Check whether the mesh was created using geographic coordinates (longitude/latitude). If so, use Spherical == 1 to the control file.

If the model is correctly using a Cartesian coordinate system and the node coordinates happen to fall within the geographic coordinate range, this warning can be ignored.
