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.
