gfscompare2D, gfscompare3D - computes the difference between the
solutions in FILE1 and FILE2 for variable VAR.
This manual page documents briefly the gfscompare
command.
These programs follow the usual GNU command line syntax, with long
options starting with two dashes (`-'). A summary of options is included
below.
- -x, --mixed
- Compute error only in mixed cells.
- -m V, --min=V
- Set minimum of color scale to V (used with -S).
- -M V, --max=V
- Set maximum of color scale to V.
- -a, --abs
- Output the absolute value of the error field.
- -C, --constant
- Apply a constant shift to one of the field, minimizing the error between
the two fields (useful for pressure).
- -w, --not-weighted
- Do not use area-weighted norm estimation.
- -c, --centered
- Use error estimation for cell-centered variables.
- -p P, --period=P
- Shifts FILE1 by P along the x axis.
- -H, --histogram
- Output (error,volume) pairs for each cell used to compute the error
norms.
- -o, --output
- Output a GTS representation of the error field.
- -S, --squares
- Output an OOGL representation of the error field.
- -G, --gnuplot
- Output a gnuplot representation of the error field.
- -t, --triangulate
- Use center of mass triangulation.
- -l, --log
- Output the log10 of the absolute value of the error field.
- -f L, --full=L
- Compare only leaf cells descendants of a cell full at level L or all full
leaf cells if L = -1.
- -r, --refined
- Display error norm on the finest grid.
- -n, --nocheck
- Do not check solid fractions.
- -g C, --gradient=C
- Use the C component of the gradient of VAR.
- -v, --verbose
- Display difference statistics and other info.
- -h, --help
- Display the help and exit.
