OVERSIMPLEFOAM(1)

✨ NAME ✨

okay bestie, gather round 💖 this is overSimpleFoam, and it's part of OpenFOAM (The Open Source CFD Toolbox). That's it, that's the whole vibe check — she's one little cog in a very big, very iconic machine 🎀

---

🌸 SYNOPSIS 🌸

overSimpleFoam [OPTIONS]

like… that's the whole thing. one binary, a pile of options, go off 👑

---

🦋 DESCRIPTION 🦋

Steady-state solver for incompressible, turbulent flow.

no cap, that's what she does. steady-state, incompressible, turbulent — the holy trinity of "my flow is chaotic but at least it's not moving in time" 💅

---

💅 OPTIONS 💅

every flag, no skips, we don't gatekeep here ✨

• -case dir — point her at the case directory you wanna use instead of the cwd (she'd otherwise just assume you're already standing in it 🙈)
• -decomposeParDict file — use this specific file for the decomposePar dictionary, iykyk
• -parallel — run it in parallel 🔥 [Parallel option]
• -postProcess — only run the functionObjects, nothing else, she's just here for the post-processing moment
• -doc — pop the documentation open in your browser 🌈
• -help — short help, then she dips. bye 👋
• -help-full — the FULL help, then exit. the director's cut, the extended edition 👑

👑 ADVANCED OPTIONS 👑

this is where the real ones live, bestie. the deep cuts. the lore 🧚

• -debug-switch name=val — set the value of a registered debug switch. if you leave the value off it defaults to 1. (you can use this one multiple times, go feral)
• -fileHandler handler — override the file handler type
• -hostRoots ((host1 dir1) .. (hostN dirN)) — per-host slave root directories for distributed running. the host spec can be a regex, so yes, you can be fancy about it ✨ [Parallel option]
• -info-switch name=val — set the value of a registered info switch. default is 1 if you don't give a value. (multiple times? absolutely, go off)
• -lib name — load an extra library or a whole list of libraries (and yes, you can do it more than once)
• -listFunctionObjects — list the functionObjects 📋
• -listFvOptions — list the fvOptions
• -listRegisteredSwitches — list the switches that are registered for run-time modification (peep the -listUnsetSwitches option for more)
• -listScalarBCs — list scalar field boundary conditions, aka fvPatchField<scalar>
• -listSwitches — list switches declared in libraries (again, see -listUnsetSwitches)
• -listTurbulenceModels — list turbulenceModels 🌪️
• -listUnsetSwitches — changes up the switch listing so it shows you the values that are NOT set in etc/controlDict
• -listVectorBCs — list vector field boundary conditions, aka fvPatchField<vector>
• -noFunctionObjects — do NOT execute function objects. she's off duty 🚫
• -opt-switch name=val — set the value of a registered optimisation switch (int/bool). defaults to 1 if the value's missing. (multiple times, obviously)
• -roots (dir1 .. dirN) — slave root directories for distributed running [Parallel option]
• -doc-source — display the source code in your browser, for the girlies who like to read the source directly 📖
• -help-man — display full help in manpage format, then exit
• -help-notes — display help notes (the description) and exit
