.. note:: It is not necessary to export all files every time.
          Export large files like INFIL.DAT or TOPO.DAT only when needed.


Troubleshooting
---------------

1. If data is missing from the grid table, this message will appear. This happens when the elevation raster, roughness
   polygon, or roughness raster do not cover the whole grid.  Check the grid attributes for NULL data.
