RHOCENTRALFOAM(1)

💖 RHOCENTRALFOAM 💖

okay bestie, welcome to rhoCentralFoam — one of the OpenFOAM commands, aka part of OpenFOAM (The Open Source CFD Toolbox). yes that OpenFOAM. the CFD one. the big one. 🌀

---

✨ SYNOPSIS ✨

rhoCentralFoam [OPTIONS]

that's it. that's the whole vibe. options go in, solver magic comes out. 💅

---

🌸 DESCRIPTION 🌸

so like. rhoCentralFoam is a density-based compressible flow solver and it's built on the central-upwind schemes of Kurganov and Tadmor. iconic duo honestly, they ate. 🔥

if you're doing compressible flow and you want that central-upwind energy, this is your girl. periodt.

---

🎀 OPTIONS 🎀

• -case dir — tell it which case directory to use, instead of just vibing in the cwd (current working directory). like, "no bestie, THIS folder."
• -decomposeParDict file — use the specific file you name for the decomposePar dictionary. you get to choose. main character energy. 👑
• -dry-run — just check the case set-up, using only a single time step. no committing, no full run. it's giving "we're just talking." 🙈
• -dry-run-write — same energy but it also writes — check the case set-up and write, only using a single time step.
• -parallel — run in parallel. [Parallel option] ✨
• -postProcess — execute functionObjects only. none of the solver stuff, just the function objects doing their lil thing.
• -doc — pop the documentation open in your browser. 🦋
• -help — show the short help and dip.
• -help-full — show the FULL help and dip. the deluxe version.

---

🦋 ADVANCED OPTIONS 🦋

for when you're feeling extra. and bestie, you know we love extra. 💜

• -debug-switch name=val — set the value of a registered debug switch. if you leave the value out, the default is 1. (can be used multiple times — go off, spam it) 🐛
• -fileHandler handler — override the file handler type. you're the boss here.
• -hostRoots ((host1 dir1) .. (hostN dirN)) — per-host slave root directories for distributed running. the host specification can be a regex, so yes you can get fancy with it. [Parallel option] 🌈
• -info-switch name=val — set the value of a registered info switch. if you leave the value out, the default is 1. (can be used multiple times too, iktr)
• -lib name — load an additional library, or a whole library list. (can be used multiple times) 📚
• -listFunctionObjects — list out all the functionObjects. window shopping, basically.
• -listRegisteredSwitches — list the switches registered for run-time modification (peep the -listUnsetSwitches option for more).
• -listScalarBCs — list scalar field boundary conditions (fvPatchField<scalar>).
• -listSwitches — list the switches declared in libraries (again, peep the -listUnsetSwitches option).
• -listTurbulenceModels — list the turbulenceModels. chaotic but make it ✨structured✨.
• -listUnsetSwitches — changes the switch listing so it displays values that are not set in etc/controlDict. sneaky lil feature, lowkey useful.
• -listVectorBCs — list vector field boundary conditions (fvPatchField<vector>).
• -noFunctionObjects — do NOT execute function objects. hard pass, apparently.
• -opt-switch name=val — set the value of a registered optimisation switch (int/bool). if you leave the value out, the default is 1. (can be used multiple times)
• -roots (dir1 .. dirN) — slave root directories for distributed running. [Parallel option] ✨
• -doc-source — open the source code in your browser. for the girlies who need to see the receipts. 😌
• -help-man — display the full help in manpage format, then exit. (hi, that's literally what you're reading rn 💀)
• -help-notes — display the help notes (the description) and exit.

and that's the whole page, bestie!! 🎀 this lil slice of the OpenFOAM commands manual came to you from www.openfoam.com, running the OpenFOAM- version, filed under RHOCENTRALFOAM(1). slay, stay compressible, and may your schemes always be central-upwind. 🦋💜✨
