This is an example 3D configuration for a glacier fjord using icefornt pkg.

This example simulates a glacier fjord of 500 m deep, 500 m long along the fjord, and 150 m
wide across the fjord. A tidewater glacier is terminated at the edge of the fjord, with a 
vertical calving face of 150 m wide and 500 m high, in contact with sea water. A channel of 
1-m high and 2-m wide exists at the bottom of the glacier, where freshwater at freezing point 
flows to the ocean at the speed of 0.5 m/s. The channel is created using shelfice pkg, and 
water T/S/V in the channel is prescribed using obcs pkg. Melt rate at the vertical ice face 
is calculated using icefront pkg.

More details of this experiment are described in the paper: 
(Xu et al.(2013), Subaqueous melting of Store Glacier, west Greenland from three-dimensional, 
 high-resolution numerical modeling and ocean observations. Geophys. Res. Lett., 40, 
 doi:10.1002/grl.50825.)

NOTE: Set dumpFreq in data or set negative frequency in data.diagnostic to get turbulence 
snapshots in Fig.2a-f of Xu et al., (2013).
