gfscompare

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.
