OVERINTERDYMFOAM(1)

🌊 overInterDyMFoam — the manual, but make it make sense 💖

okay so bestie, you're looking at overInterDyMFoam, which is literally part of OpenFOAM (that's The Open Source CFD Toolbox, no cap) 👑 She's a whole command, she lives in your terminal, and she's about to do some very serious fluid physics while looking absolutely unbothered. Let's get into it 🦋

---

✨ SYNOPSIS ✨

overInterDyMFoam [OPTIONS]

that's it. that's the whole summoning ritual. you say her name, you hand her some options, and she goes 💅

---

🫶 DESCRIPTION 🫶

So what does she actually do, you ask? She is a solver for two incompressible, isothermal immiscible fluids using VOF phase-fraction based interface capturing. Two fluids, both incompressible, both isothermal, both refusing to mix (immiscible, periodt) — and she tracks the boundary between them with VOF phase-fraction based interface capturing. The interface is the main character here, and she's giving it the full portrait treatment 🌈

And if that wasn't enough — she does all of this with optional mesh motion and mesh topology changes including adaptive re-meshing. Like, the mesh can literally move and reshape itself underneath her and she just keeps going. Iconic behaviour, honestly. Not me being obsessed with a solver 🎀

💅 OPTIONS 💅

here's the full menu, bestie, every single one, nothing skipped:

• -case dir — point her at the case directory you want to use, instead of just vibing in the current working directory (cwd).
• -decomposeParDict file — use file as the decomposePar dictionary, if you want to override which one she reads.
• -parallel — run in parallel. this is a [Parallel option], so she'll want friends 💜
• -postProcess — execute functionObjects only. that's the whole job for this run, nothing else.
• -doc — pops the documentation open in your browser. wiki moment 🦋
• -help — short help, then she dips.
• -help-full — the full help, then she dips. deluxe edition ✨

---

🌸 ADVANCED OPTIONS 🌸

these are the deep cuts, iykyk. still all facts, just fancier 💖

• -debug-switch name=val — set the value of a registered debug switch. if you don't give a value, the default is 1. (you can use this multiple times, go wild)
• -fileHandler handler — override the file handler type.
• -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 spicy with it. [Parallel option]
• -info-switch name=val — set the value of a registered info switch. default is 1 if you omit the value. (can be used multiple times, again, no judgement)
• -lib name — load an additional library or library list. (can be used multiple times — stack 'em up 🍓)
• -listFunctionObjects — list the functionObjects. show me the functionObjects 📋
• -listFvOptions — list the fvOptions.
• -listRegisteredSwitches — list switches registered for run-time modification (peep the -listUnsetSwitches option if you want the other flavour).
• -listScalarBCs — list scalar field boundary conditions (fvPatchField<scalar>).
• -listSwitches — list switches declared in libraries (again, see the -listUnsetSwitches option).
• -listTurbulenceModels — list the turbulenceModels.
• -listUnsetSwitches — modifies the switch listing so it displays values that are not set in etc/controlDict. sneaky peek energy 👀
• -listVectorBCs — list vector field boundary conditions (fvPatchField<vector>).
• -noFunctionObjects — do not execute function objects. the opposite of -postProcess, basically.
• -opt-switch name=val — set the value of a registered optimisation switch (int/bool). default is 1 if you omit the value. (can be used multiple times)
• -roots (dir1 .. dirN) — slave root directories for distributed running. [Parallel option]
• -doc-source — opens the source code in your browser. yes, the actual source. go read it, nerd (affectionate) 🧚
• -help-man — full help in manpage format, then exit.
• -help-notes — help notes, i.e. the description, then exit.

heads up bestie: -parallel is marked as a [Parallel option], and so are -hostRoots and -roots. those three are the parallel squad — don't expect them to make sense on their own 💀
