Example: "Flow over a bump with Open Boundaries and passive tracers"

default paths are (as used in testreport):

set build_dir = ${cwd}/build
set run_dir   = ${cwd}/run
set ROOT      = ${cwd}/../../

Configure and compile the code:

cd ${build_dir}
${ROOT}/tools/genmake2 -mods ../code [-of my_platform_optionFile]
make depend
make
cd ..

To run:

cd ${run_dir}
ln -s ../input/* .
${build_dir}/mitgcmuv > output.txt
cd ..

There is comparison output in the directory: results ( absolute path: ${run_dir}/../results )

Comments: The input data is real*8.

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