Output

There are two categories of output commands:

1. Locations
   commands defining sets of output locations at which the user requires output. Each set is indicated with a name ('sname' in this manual) which must be unique and not more than 8 characters long.
   
   
   Types of sets of output points:
   

   FRAME	to define a set of output locations on a regular grid
   GROUP	to define a set of output locations on a regular or curvilinear grid
   CURVE	to define a set of output locations along a curve
   RAY	to define a set of output locations along a depth or bottom contour line
   	(with ISOLINE)
   ISOLINE	to define a set of output locations along a depth- or bottom contour line
   	(with RAY)
   POINTS	to define a set of isolated output locations
   NGRID	to define a set of output locations for a nested grid to be used in a
   	subsequent SWAN run

   
   

   Commands FRAME, GROUP, RAY, ISOLINE and NGRID cannot be used in 1D-MODE and command GROUP cannot be used in case of unstructured meshes. If one gives one name for two sets of output locations, the first set is lost (first in the sequence in the command file). Two special names BOTTGRID and COMPGRID are reserved for use by SWAN (see below). The user may not define sets with these names.

2. Write / plot
   commands defining data file output (write) at the above defined set(s) of output locations:
   

   BLOCK	write spatial distributions (only for FRAMEs and GROUPs)
   TABLE	write output for (set of) output location(s)
   SPECOUT	write to data file the variance / energy (see command SET) density
   	spectrum for (set of) output location(s)
   NESTOUT	write to data file two-dimensional action density spectra (relative frequency)
   	along the boundary of a nested grid (see command NGRID) to be used in a
   	subsequent SWAN run.

   
   

   Commands BLOCK and NESTOUT cannot be used in 1D-MODE.
