In the program the flag arrays are usually called FLZ
(Z-grid) and FLM (M-grid).
They have Fortran type INTEGER.
In call-lists the array names are usually followed by the size
parameters
(M,N) and
the grid type ('Z' or 'M')
The interpretation function INSPFL is found in OTEQ/s/oteu011.f
Files containing flag arrays are usually called
FLZ.DAT - Unresolved flags Z-grid (for use
with
elvations, potentials)
FLZU.DAT - Flags with active boundaries etc
resolved
FLM.DAT - Unresolved flags M-grid (for use
with
currents and depth)
FLMH.DAT - Contains FLM and depth
The /CAREA/ information about grid spacing,
projection
and area location
is usaually appended to FLZU.DAT
The status is indicated by a flag value exceeding 110,000. In the
unresolved
state
the number is 200,000+C where C is usually 0. Only
in
the case of an M-grid
node at the intersection with land C is the passive
boundary
condition number.
The flag value is in the resolved state 200,000-K where K
is the
storage address.
The storage that is addressed contains tide elevation retrieved
from
an external
(global) model.
The status is indicated by a number 100,000 (unresolved state)
In the resolved state the value is -K where K is the storage address.
The storage that is addressed contains tide elevation retrieved
from
an external
(global) model.
