**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 thegfscomparecommand.

**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,--mixedCompute error only in mixed cells.-mV,--min=VSet minimum of color scale to V (used with -S).-MV,--max=VSet maximum of color scale to V.-a,--absOutput the absolute value of the error field.-C,--constantApply a constant shift to one of the field, minimizing the error between the two fields (useful for pressure).-w,--not-weightedDo not use area-weighted norm estimation.-c,--centeredUse error estimation for cell-centered variables.-pP,--period=PShifts FILE1 by P along the x axis.-H,--histogramOutput (error,volume) pairs for each cell used to compute the error norms.-o,--outputOutput a GTS representation of the error field.-S,--squaresOutput an OOGL representation of the error field.-G,--gnuplotOutput a gnuplot representation of the error field.-t,--triangulateUse center of mass triangulation.-l,--logOutput the log10 of the absolute value of the error field.-fL,--full=LCompare only leaf cells descendants of a cell full at level L or all full leaf cells if L = -1.-r,--refinedDisplay error norm on the finest grid.-n,--nocheckDo not check solid fractions.-gC,--gradient=CUse the C component of the gradient of VAR.-v,--verboseDisplay difference statistics and other info.-h,--helpDisplay the help and exit.
