OVERCOMPRE...TERDYMFOAM(1)

📦 version 2512, in nixpkgs unstable

👑 overCompressibleInterDyMFoam (1) — the OpenFOAM Commands Manual, bestie edition

okay so this is overCompressibleInterDyMFoam, and yes she's part of OpenFOAM (The Open Source CFD Toolbox) — literally the whole icon situation. no cap, this is the glow-up you've been waiting for 💅✨

🌸 SYNOPSIS 🌸

overCompressibleInterDyMFoam [OPTIONS]

💖 DESCRIPTION 💖

bestie. this is THE solver for two compressible, non-isothermal, immiscible fluids — like three whole vibes going on at once and she's serving all of them 🫶. she uses the VOF phase-fraction based interface capturing approach (iykyk), and she supports dynamic mesh motions including overset cases. the way she handles moving meshes? iconic. main character energy fr fr 💀✨

✨ OPTIONS ✨

okay so here's the full lineup, no skips, every single one is getting her moment 👑

  • -case dir — case directory (instead of the current directory, because sometimes you don't wanna be where you are, and honestly, valid)
  • -decomposeParDict file — alternative decomposePar dictionary file, for when the default just isn't giving
  • -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
  • -parallel — run in parallel [Parallel option] — she's doing the most, simultaneously 🌈
  • -postProcess — execute functionObjects only
  • -doc — display documentation in the browser 🔥
  • -help — display short help and exit
  • -help-full — display full help and exit

🎀 ADVANCED OPTIONS 🎀

these are for the girlies who go deeper. the advanced girlypops. the ones who read the whole README 🧚

  • -debug-switch name=val — set named DebugSwitch (default value: 1). [Can be used multiple times] — yes you can keep adding, she's flexible
  • -fileHandler handler — override the file handler type
  • -hostRoots ((host1 dir1) .. (hostN dirN)) — per-subprocess root directories for distributed running. the host specification can be a regex. [Parallel option]
  • -info-switch name=val — set named InfoSwitch (default value: 1). [Can be used multiple times]
  • -lib name — additional library, or a library list, to load. [Can be used multiple times]
  • -listFunctionObjects — list functionObjects
  • -listFvOptions — list fvOptions
  • -listRegisteredSwitches — list switches registered for run-time modification (see the -listUnsetSwitches option, she's linked)
  • -listScalarBCs — list scalar field boundary conditions (fvPatchField<scalar>)
  • -listSwitches — list switches declared in libraries (see the -listUnsetSwitches option)
  • -listTurbulenceModels — list turbulenceModels
  • -listUnsetSwitches — modifies the switch listing to display values not set in etc/controlDict
  • -listVectorBCs — list vector field boundary conditions (fvPatchField<vector>)
  • -mpi-no-comm-dup — disable the initial MPI_Comm_dup()
  • -mpi-split-by-appnum — split the world communicator based on the APPNUM
  • -mpi-threads — request use of MPI threads
  • -no-libs — disable use of the controlDict 'libs' entry
  • -noFunctionObjects — do not execute function objects
  • -opt-switch name=val — set named OptimisationSwitch (default value: 1). [Can be used multiple times]
  • -roots (dir1 .. dirN) — subprocess root directories for distributed running [Parallel option]
  • -world name — name of the local world for parallel communication [Parallel option]
  • -doc-source — display source code in the browser 👀
  • -help-man — display full help (manpage format) and exit
  • -help-notes — display help notes (the description bit) and exit
💀 lowkey important: options marked [Parallel option] and [Can be used multiple times] keep those exact vibes — don't come for me if you ignore the brackets, that's on you bestie
