! PROGRAM SWANCOM5.FOR
!
! This file SWANCOM5 of the main program SWAN
! includes the next subroutines (mainly subroutines for
! the propagation in x,y,s,d space and parameters ) :
!
! SWGEOM ( determines geometric quantities )
! SWPSEL ( determine spectral counters in presence
! or absence of a current )
! SPROXY ( compute spatial propagation velocities CAX, CAY )
! SPROSD ( compute spectral propagation velocities CAS, CAD )
! DSPHER ( compute Ctheta for propagation over the globe ) 33.09
! STRSXY ( compute derivative in space and time )
! SORDUP ( compute spatial derivatives with SORDUP scheme ) 33.10
! SANDL ( compute spatial derivatives with S&L scheme ) 33.08
! STRSSI ( compute derivative in s-space implicit scheme )
! STRSSB ( compute derivative in s-space explicit scheme and
! remove (or dissipate bin's that are blocked) )
! STRSD ( compute derivative in d-space implicit )
! SPREDT ( calculate action density in central point: first guess )
! SWAPAR ( compute wave parameters k, cgo and cg )
! ADDDIS ( adds leak and dissipation to arrays in COMPDA, after
! action densities have been computed )
! SWFLXD ( compute derivative in theta-space by means of 40.23
! flux-limiting )
! DIFPAR ( compute diffraction parameter and its derivatives ) 40.21

! 2. PURPOSE
!
! compute the frequency dependent counters in directional space
! in a situation with a current and without a current.
! The counters are only computed for the gridpoint
! considered. This means IC = 1 (see loop with CALL for ICCODE
! function)
!
! 3. METHOD
!
! In absence of a current the fully 360 degrees sector is
! subdivided in 4 sectors of 90 degrees each.
!
! In presence of a current this is not the case anymore. The
! counters of the directional space are frequency dependent.
! It is first determined which bins have to taken into account
! for a particular sweep (unconditionally stable for a specific
! sector). To which sector a bin belongs is determined by its
! propagation velocity Cx and Cy.
!
! For the first sweep, all the bins with a positive propagation
! velocity Cx and Cy have to taken into account.
! For one particular frequency IS:
!
!
! #
! - # + +
! - # + CAX, CAY > 0
! - # |
! IDCMAX # ..*..*..* +
! - #\.....|.....*
! *# \...|.......* +
! - # \.|........
! --*-#------O--------*-- +
! # | \......
! - *# | \...* +
! # # # # # # # # # # # # # # # # # #\# # # # # # # # #
! # * * * IDCMIN
! - # | -
! #
! # -
! - #
! -
! - -
! - - -
!
!
! As can be seen from the figure, the minimum and maximum
! counter of the directional space are determined by the
! vectorial sum of its groupvelocity and its current
! velocity, c_g + U. Especially the higher frequencies are
! modified by the current. The lower frequencies (due to
! the larger propagation velocity) are less modified by a
! current.
!
! In general, we can distinguish 4 cases:
!
! SWEEP 1:
! ..*..
! *.........*
! |. ............ | *..*
! | | *| ..o.......* | *......*
! | *|* |...... ....... | *......*
! | * |..* |*... ....* | *..*
! -----|----- -*---|---*- -----|--*-------*-- ---|-------------
! | * | * | * |
! * * | *|* | |
! * *| | | |
! * *
!
! SECTOR = 0 SECTOR = 2 SECTOR = 4 SECTOR = 1
!
!
! The integer array SECTOR denotes which case is present for
! a certain frequency:
!
! 0 : no bins belongs to first sweep, no sector lies within the
! first sweep
! 2 : circle has 2 intersections with sector boundary
! 4 : circle has 4 intersections with sector boundary
! 1 : full circle lies within the first quadrant, all directions
! have to taken into account
!
! Furthermore it is detemined whether a certain BIN lies within
! a specific quadrant. This is denoted by a logical array ANYBIN
! In case of SECTOR = 4, this array is used to clear the rows
! in the matrix IMATDA, IMATRA, IMATLA, IMATUA, which do not
! belong to the first (or other) sweep (see subroutine SOLPRE).

! 1. UPDATE
!
! 40.13, Oct. 01: loop over IC now inside this subroutine
! 40.21, Aug. 01: adaption of velocities in case of diffraction
! 40.41, Oct. 04: common blocks replaced by modules, include files removed
!
! 2. PURPOSE
!
! computes the propagation velocities of energy in X-, Y-
! -space, i.e., CAX, CAY, in the presence or absence of
! currents, for the action balance equation.
!
! The propagation velocities are computed for the fully 360
! degrees sector.
!
! 3. METHOD
!
! The next equation are calculated:
!
! @X _
! CAX = -- = n C cos (id) + Ux = CGO cos(id) + Ux
! @T
!
! @Y _
! CAY = -- = n C sin(id) + Uy = CGO sin(id) + Uy
! @T
! _
! 4. PARAMETERLIST
!
! IC Dummy variable: ICode gridpoint:
! IC = 1 Top or Bottom gridpoint
! IC = 2 Left or Right gridpoint
! IC = 3 Central gridpoint
! Whether which value IC has, depends of the sweep
! If necessary ic can be enlarged by increasing
! the array size of ICMAX
! IX Counter of gridpoints in x-direction
! IY Counter of gridpoints in y-direction
! IS Counter of relative frequency band
! ID Counter of directional distribution
! ICUR Indicator for current
! ICMAX Maximum array size for the points of the molecule
! MXC Maximum counter of gridppoints in x-direction
! MYC Maximum counter of gridppoints in y-direction
! MSC Maximum counter of relative frequency
! MDC Maximum counter of spectral directions
!
! REAL:
! ----
! COEF auxiliary coefficient
! VLSINH value of the SINH for a certain value of 2KD
