gfscompare(1) User Commands gfscompare(1)

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.

Compute error only in mixed cells.
Set minimum of color scale to V (used with -S).
Set maximum of color scale to V.
Output the absolute value of the error field.
Apply a constant shift to one of the field, minimizing the error between the two fields (useful for pressure).
Do not use area-weighted norm estimation.
Use error estimation for cell-centered variables.
Shifts FILE1 by P along the x axis.
Output (error,volume) pairs for each cell used to compute the error norms.
Output a GTS representation of the error field.
Output an OOGL representation of the error field.
Output a gnuplot representation of the error field.
Use center of mass triangulation.
Output the log10 of the absolute value of the error field.
Compare only leaf cells descendants of a cell full at level L or all full leaf cells if L = -1.
Display error norm on the finest grid.
Do not check solid fractions.
Use the C component of the gradient of VAR.
Display difference statistics and other info.
Display the help and exit.
