TUFLOW Message 2825
WARNING 2825 - More than one level one nesting polygon found. Will only use one polygon with nesting level of 1. Overriding previously processed polygon.
More than one level one nesting polygons are found. The last level 1 nesting polygon read by TUFLOW will override any level 1 nesting polygons processed previously.
Check the nesting levels of the polygons and make sure the level 1 nesting polygon is specified correctly. Note that level 1 nesting polygon is NOT required if the model origin and extent are defined in the .tgc file. In this situation, the rectangle representing the .tgc computational domain is used as the level 1 polygon.
