It is possible to define more than one boundary ``set'' and apply different boundary conditions to each set.
The number of boundary sets is defined by \np{nb_bdy}{nb\_bdy}.
Each boundary set can be either defined as a series of straight line segments directly in the namelist
-(\np[=.false.]{ln_coords_file}{ln\_coords\_file}, and a namelist block \forcode{&nambdy_index} must be included for each set) or read in from a file (\np[=.true.]{ln_coords_file}{ln\_coords\_file}, and a ``\textit{coordinates.bdy.nc}'' file must be provided).

The coordinates.bdy file is analagous to the usual \NEMO\ ``\textit{coordinates.nc}'' file.
-In the example above, there are two boundary sets, the first of which is defined via a file and
-the second is defined in the namelist.

+In the example above, there are two boundary sets, the first of which is defined via a file (namelist \ref{lst:nambdy}) and

+For more details of the definition of the boundary geometry and coordinate files see section \autoref{subsec:LBC_bdy_geometry}.
For each boundary set a boundary condition has to be chosen for the barotropic solution
(``u2d'':sea-surface height and barotropic velocities), for the baroclinic velocities (``u3d''),
