bd2e7b4f6b Mart*0028 This experiment is a channel with topography and four open
                0029 boundaries. Salinity is not dynamically active in this experiment
                0030 (linear equation of state with sBeta=0). Different kinds of open
                0031 boundary values are used: zonal (x-)velocity U is prescribed at all
                0032 open boundaries with values that are read from data files (specified
                0033 in data.obcs); meridional (y-)velocity V is set to zero on all
                0034 boundaries, and temperature to tRef(z), both in obcs_calc.F, this is
                0035 the default behavior; at the western boundary, salinity values are
                0036 used for salinity and one passive tracer in the same way. Salinity is
                0037 set to sLev at all other boundaries, while a (nearly) homogeneous
                0038 v.Neumann condition is applied to the passive tracer (the latter is
6c607fc2ca Jean*0039 the default in obcs_calc.F), with a relaxation (using pkg rbcs) in
                0040 the Eastern part of the channel. Open boundary parameters are set in
bd2e7b4f6b Mart*0041 data.obcs.
