68 Chapter 4 [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
Description of commands 69 (see below). The locations are determined by SWAN as the intersections of the depth contour line(s) and the set of straight rays defined in this command RAY. These rays are characterized by a set of master rays defined by their start and end positions ([xp],[yp]) and ([xq],[yq]). Between each pair of sequential master rays thus defined SWAN generates [int]−1 intermediate rays by linear interpolation of the start and end positions. Note that the rays thus defined have nothing in common with wave rays (e.g. as obtained from conventional refraction computations). ’rname’ name of the set of rays defined by this command. [xp1],[yp1],problem coordinates of the begin and end points of the first master ray [xq1],[yq1] if Cartesian coordinates are used in m if spherical coordinates are used in degrees (see command COORD) [int] number of subdivisions between the previous master ray and the following master ray defined by the following data (number of subdivisions is one more than the number of interpolated rays) [xp],[yp], problem coordinates of the begin and end points of each subsequent master ray [xq],[yq] if Cartesian coordinates are used in m if spherical coordinates are used in degrees (see command COORD) | -> DEPth | ISOline ’sname’ ’rname’ < > [dep] | BOTtom | CANNOT BE USED IN 1D-MODE. With this optional command the user defines a set of output locations along one depth or bottom level contour line (in combination with command RAY). ’sname’ ’rname’ [dep] name of the set of output locations defined by this command name of the set of rays (as defined in command RAY) the depth (in m) of the depth contour line along which output locations are generated by SWAN. If the keyword DEPTH appears in front of the value the true depth is used, if the keyword BOTTOM appears the water level is ignored, i.e. the depth with respect to datum level is used. The set of output locations along the depth contour lines created with this command is of the type CURVE.
