with a 3D child grid PyNEMO crashes if 2D boundary data is specified
Created by: thopri
At the moment PyNEMO crashes if you specify 2D data for a 3D grid. e.g. SSH or ICE with the benchmark child grid.
I am going to handle it for now with a try except to catch the error and raise an exception so that users will know a potential cause for it. (Error is a bit opaque at the mo.)
I was wondering if it was sensible to make it so PyNEMO can handle this, e.g. by slicing the surface layer of the child grid and making it 2D? would need to add warnings etc in the log but could be useful?
