DRIFTFLUXFOAM(1)

💖 DRIFTFLUXFOAM 💖

okay bestie, so this one lives in the OpenFOAM Commands Manual (that's the Open Source CFD Toolbox, no cap) and it's a whole solver. let's get into it 🫶

---

✨ NAME ✨

driftFluxFoam — part of OpenFOAM (The Open Source CFD Toolbox). that's the whole name, she's lowkey mysterious like that 💅

---

✨ SYNOPSIS ✨

driftFluxFoam [OPTIONS]

---

✨ DESCRIPTION ✨

okay so picture this: it's a solver for two incompressible fluids using the mixture approach, with the drift-flux approximation handling the relative motion of the phases. it's giving physics but make it ✨relative✨

it's used for simulating the settling of the dispersed phase and other similar separation problems. so like, when stuff separates out and one phase settles — that's her moment, that's her main character energy 👑

---

✨ OPTIONS ✨

• -case dir — tell her which case directory to use instead of the cwd. (the cwd is so last season, we love a specified directory 💖)
• -decomposeParDict file — use the specified file for the decomposePar dictionary. custom dict? iconic.
• -dry-run — check the case set-up only, using a single time step. a little vibe check before the real thing 🦋
• -dry-run-write — check the case set-up and write, only using a single time step. vibe check + actually commit to the bit.
• -parallel — run in parallel. [Parallel option] she's bringing the whole friend group 🫂
• -postProcess — execute functionObjects only. no solving, just the little extras ✨
• -doc — display documentation in browser. reading is fundamental bestie 📖
• -help — display short help and exit. the quick version, for when you're in a rush 🏃
• -help-full — display full help and exit. the deluxe version, all the tea ☕

🌸 ADVANCED OPTIONS 🌸

• -debug-switch name=val — specify the value of a registered debug switch. the default is 1 if the value is omitted. (can be used multiple times — go off, stack them 💅)
• -fileHandler handler — override the file handler type. you're in charge of the handler now, queen.
• -hostRoots ((host1 dir1) .. (hostN dirN)) — per-host slave root directories for distributed running. the host specification can be a regex. [Parallel option] so fancy ✨
• -info-switch name=val — specify the value of a registered info switch. default is 1 if the value is omitted. (can be used multiple times 🎀)
• -lib name — additional library or library list to load (can be used multiple times). collect them all 🌈
• -listFunctionObjects — list functionObjects. a little show-and-tell.
• -listFvOptions — list fvOptions. same energy, different list 💜
• -listRegisteredSwitches — list switches registered for run-time modification (see the -listUnsetSwitches option). iykyk.
• -listScalarBCs — list scalar field boundary conditions (fvPatchField<scalar>). scalars say hi 👋
• -listSwitches — list switches declared in libraries (see the -listUnsetSwitches option). library switches, the whole crew 🫶
• -listUnsetSwitches — modifies switch listing to display values not set in etc/controlDict. the ones that didn't show up to the party 🙈
• -listVectorBCs — list vector field boundary conditions (fvPatchField<vector>). now the vectors get their turn ⭐
• -noFunctionObjects — do not execute function objects. sorry girlies, they're not coming 💀
• -opt-switch name=val — specify the value of a registered optimisation switch (int/bool). default is 1 if the value is omitted. (can be used multiple times 🔥)
• -roots (dir1 .. dirN) — slave root directories for distributed running [Parallel option]. roots, but make them distributed 🌱
• -doc-source — display source code in browser. going straight to the source, ngl.
• -help-man — display full help (manpage format) and exit. hi, that's literally what you're reading 💖
• -help-notes — display help notes (description) and exit. the notes version, for the lore 📝

just a heads up: -parallel, -hostRoots and -roots are all tagged as [Parallel option], and both -listRegisteredSwitches and -listSwitches point you at -listUnsetSwitches for the full picture. also -debug-switch, -info-switch, -opt-switch and -lib can each be used multiple times. don't forget it 🫶

and that's the whole page, bestie 💅 source and version, as promised: www.openfoam.com, OpenFOAM- — that's the version string, she's a little cryptic but we love her anyway 🎀✨ go simulate something gorgeous, mwah 💖
