Tous les systèmes hamiltoniens intégrables se ressemblent, mais chacun qui est non intégrable, il est non intégrable à sa manière
DESCRIPTION
The gfs-csv utility reads gfs files produced by gerris2D (1) simulations and writes scalar fields defined in them to a uniform grid, as x, y, z CSV data.
Such output data can be processed with many other programs, in particular the GMT (1) suite of plotting programs. The main purpose is to simplify the plotting of Gerris scalars (such as vorticity) alongside the arrows produced by vfplot (1) .
OPTIONS
-
-d
--delimiter
character
-
Use the passed
character
as delimiter in the output rather than the default comma. -
-h
--help
-
Brief help.
-
-i
--index
-
Write the i, j indices instead of x, y values.
-
-o
--output
file
-
Write output to
file
rather than standard output. -
-s
--scalar
name
-
Specify the scalar quantity to extract from the file. The argument can be a GtsVariable such as "Vorticity", or a GtsFunction such as "(Vorticity/2.0 + U)". In the latter case take care to quote shell metacharacters.
This option must be specified at least once, and may be specified multiple times; the effect being to have the columns corresponding to these in the output CVS file.
-
-v
--verbose
-
Verbose operation.
-
-V
--version
-
Version information.
