284	Use of boundary arrays	arango	arango	"The boundary arrays are now strictly defined and allocated when they are really needed. There are several internal options to do so:
{{{
EAST_FSOBC, WEST_FSOBC, SOUTH_FSOBC, NORTH_FSOBC
EAST_M2OBC, WEST_M2OBC, SOUTH_M2OBC, NORTH_M2OBC
EAST_M3OBC, WEST_M3OBC, SOUTH_M3OBC, NORTH_M3OBC
EAST_TOBC,  WEST_TOBC,  SOUTH_TOBC,  NORTH_TOBC
}}}
These C-preprocessing options are defined in '''globaldefs.h''' and there is not need for the user to manually activate them.  However, it is wise to use them in the
analytical routines '''ana_fsobc.h''', '''ana_m2obc.h''', '''ana_m3obc.h''', and '''ana_tobc.h'''.  Sometimes anlytical expressions are coded but not used when playing with various set-ups in the test problems.

There are couple of messages in the forum reporting compilation problems with unused analytical expressions. Using the above options in such expressions solve such compilation errors.
