gfscompare(1)

💖 gfscompare — the bestie guide 💖

okay so hi!! welcome to gfscompare, a User Commands classic, and honestly? she's iconic. this is the page for gfscompare2D and gfscompare3D from the gfscompare manual, and she does one very important thing: she computes the difference between the solutions in FILE1 and FILE2 for variable VAR. that's it, that's the job, and she eats every time. 🍓

✨ 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. short, sweet, to the point — like a text you send at 2am that somehow says everything. ✨

👑 OPTIONS 👑

These programs follow the usual GNU command line syntax, with long options starting with two dashes (-). A summary of options is included below. no cap, every single one is here, so let's get into it bestie 🫶

• -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.

and that's the whole page!! every flag, every value, every default, nothing skipped, we keep it exactly as it was — the facts stay, the vibe just got cuter 💖

this little gem is gfscompare(1), dropped on July 10, 2008, and she's still serving. mwah, love u, go compare some fields bestie 💅✨🦋
