[ix1] ≤ ix ≤ [ix2] and [iy1] ≤ iy ≤ [iy2]
For convenience the size of the group, the corner coordinates and the angle with the
problem coordinate system are written to PRINT file. The origin of the computational grid
is (ix=0,iy=0)!
’sname’
[ix1]
[iy1]
[ix2]
[iy2]
name of the set of output locations defined by this command
lowest grid index of subgrid in terms of computational grid in ix-direction
lowest grid index of subgrid in terms of computational grid in iy-direction
highest grid index of subgrid in terms of computational grid in ix-direction
highest grid index of subgrid in terms of computational grid in iy-direction
Limitations:
[ix1]≥0, [ix2]≤[mxc], [iy1]≥0, [iy2]≤[myc] ([mxc] and [myc] as defined in the
command CGRID).
CURve ’sname’ [xp1] [yp1] < [int] [xp] [yp] >
With this optional command the user defines output along a curved line. Actually this
curve is a broken line, defined by the user with its corner points. The values of the output
quantities along the curve are interpolated from the computational grid. This command
may be used more than once to define more curves.
’sname’ name of the curve
[xp1],[yp1] problem coordinates of the first point of the curve
if Cartesian coordinates are used in m
if spherical coordinates are used in degrees (see command COORD)
[int] SWAN will generate output at [int]−1 equidistant locations between two
subsequent corner points of the curve (including the two corner points of the curve)
[xp],[yp] problem coordinates of a corner point of the curve. Repeat the group
[int] [xp] [yp] in proper order if there are more corner points are on the curve.
RAY ’rname’ [xp1] [yp1] [xq1] [yq1] < [int] [xp] [yp] [xq] [yq] >
CANNOT BE USED IN 1D-MODE.
With this optional command the user provides SWAN with information to determine output
locations along the depth contour line(s) defined subsequently in command ISOLINE
