NAME

gfscompare2D, gfscompare2D3, 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.
