NAME
gfscompare2D, gfscompare3D - computes the difference between the solutions in FILE1 and FILE2 for variable VAR.
SYNOPSIS
gfscompare [OPTION]FILE
DESCRIPTION
This manual page documents briefly the gfscompare command.
OPTIONS
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.
