Check Files 2d to 2d bc

This GIS check file layer contains more information on the 2D/2D boundary links. Boundary cells from both domains are output as region objects. Please refer to the TUFLOW documentation for more information on the 2D 2D linking method.
This layer is output only if a model uses multiple 2D domains.
