All integrable Hamiltonian systems are alike, while each nonintegrable one is nonintegrable in its own way
DESCRIPTION
The gfs2xyz2D utility reads gfs files produced by gerris2D(1) simulations and writes scalar fields defined in them to a uniform grid, as x, y, z ASCII column data.
Such output data can be processed with many other programs, in particular the GMT(1) suite of plotting programs.
OPTIONS
-h, --help
-
Brief help.
-i, --index
-
Write the i, j indices instead of x, y values.
-o, --output
file
-
Plot 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.
-S, --sag
-
Add a sag(5) header to the output data.
-v, --verbose
-
Verbose operation.
-V, --version
-
