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.
