💖 DNSFOAM(1) 💖

okay bestie, welcome to the OpenFOAM Commands Manual — this is dnsFoam, part of OpenFOAM (The Open Source CFD Toolbox). she's the whole point of this page, so let's get into it 🦋

✨ SYNOPSIS ✨

dnsFoam [OPTIONS]

🌸 DESCRIPTION 🌸

Direct numerical simulation for boxes of isotropic turbulence. that's it, that's the vibe — she does DNS on lil boxes of turbulence and she does it flawlessly. no cap 💅

🎀 OPTIONS 🎀

  • -case dir — pick the case directory you wanna work in, instead of just using the cwd. lowkey essential, ngl.
  • -decomposeParDict file — use this specific file for the decomposePar dictionary instead of whatever the default would be.
  • -parallel — run it in parallel. [Parallel option] ✨
  • -postProcess — only execute the functionObjects, nothing else. just the lil extras, bestie.
  • -doc — pops the documentation open in your browser. 🌈
  • -help — short help, then she's out. bye 👋
  • -help-full — the full help, then exit. the deluxe version 💖

👑 ADVANCED OPTIONS 👑

  • -debug-switch name=val — set the value of a registered debug switch. if you leave the value out it defaults to 1. (can be used multiple times — go off, stack them) 🍓
  • -fileHandler handler — override the file handler type. she said "not today, default." 💅
  • -hostRoots ((host1 dir1) .. (hostN dirN)) — per-host slave root directories for distributed running. the host specification can be a regex, which is iconic. [Parallel option]
  • -info-switch name=val — set the value of a registered info switch. defaults to 1 if you omit the value. (can be used multiple times) 🧚
  • -lib name — an additional library or library list to load. (can be used multiple times — collect them like stickers) ✨
  • -listFunctionObjects — lists all the functionObjects. 👑
  • -listRegisteredSwitches — lists switches registered for run-time modification. (see the -listUnsetSwitches option for more) 💜
  • -listScalarBCs — lists scalar field boundary conditions (fvPatchField<scalar>). 🎀
  • -listSwitches — lists switches declared in libraries. (see the -listUnsetSwitches option) 🌸
  • -listUnsetSwitches — changes up the switch listing so it shows values that are not set in etc/controlDict. sneaky but useful 🫶
  • -listVectorBCs — lists vector field boundary conditions (fvPatchField<vector>). ⭐
  • -noFunctionObjects — do not execute function objects. the opposite of -postProcess, if you will 😭
  • -opt-switch name=val — set the value of a registered optimisation switch (int/bool). defaults to 1 if you omit the value. (can be used multiple times) 🔥
  • -roots (dir1 .. dirN) — slave root directories for distributed running. [Parallel option] 🌈
  • -doc-source — pops the source code open in your browser. main character energy 📖
  • -help-man — the full help, in manpage format, then exit. yes bestie, that's the format you're reading rn 💀
  • -help-notes — shows the help notes (the description) and exits. 🙈

ok that's the whole page, you ate it, you understood it, periodt. 💅✨

mwah — this was dnsFoam, served up from www.openfoam.com, version OpenFOAM-, and yeah the date's a lil mysterious on this one but that's the footer's business, not ours 🦋💜
