Other flags

We explain the values of certain flags.

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
 
 

Active boundaries.

The flags are usually shown by the prflm print routine with the symbol  }

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.
 

Out-of-area.

The flags are usually shown by the prflm print routine with the symbol  o

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.
