Alternatively, if all cells are to be active (water) cells, simply use Set Code == 1.
To view the 2D mesh
A 2d_grd layer can be optionally created using Write MI Grid. This layer will be used to view the model mesh and check the 2D domain. It is not needed as an input to TUFLOW. It is recommended that this layer be placed in the “check” folder as it is mainly used to checking the 2D mesh. When you import this 2d_grd layer into the GIS, it will show you the extent of the mesh’s active cells and the status of the mesh’s attributes at that point in the .tgc file. These attributes can be used to perform thematic mapping and other quality control checks.
