SUBSETMESH(1)

💖 SUBSETMESH 💖

okay bestie, so this one is subsetMesh, and it's part of OpenFOAM (The Open Source CFD Toolbox) — you know, the whole OpenFOAM Commands Manual situation. pull up a chair, we're carving out a lil slice of mesh and it's gonna be iconic 🎀

---

✨ SYNOPSIS ✨

subsetMesh [OPTIONS] cell-selection

---

🌸 DESCRIPTION 🌸

so basically? you're making a mesh subset for a particular region of interest 🦋 — based on a cellSet or cellZone(s) that you pass as the first command argument. that's it, that's the vibe.

and if you're sitting there like "bestie how do i even pick cells" — go look at the setSet/topoSet utilities, they'll show you how to select cells based on various shapes. no cap. 💅

---

👑 ARGUMENTS 👑

• cell-selection — this is the cellSet name, periodt. but if you've got the -zone option on, it gets interpreted as a cellZone selection by name(s) or regex instead. like for example 'mixer' or '( mixer "moving.*" )' — yes, a whole lil list situation, we love to see it ✨

---

💅 OPTIONS 💅

• -case dir — tell it which case directory to use (instead of the cwd, bestie)
• -decomposeParDict file — use the specified file for the decomposePar dictionary
• -overwrite — overwrite existing mesh/results files. bold move. 😭
• -parallel — run in parallel. [Parallel option] — she's multithreaded, she's thriving 🔥
• -patch name — add exposed internal faces to the specified patch instead of "oldInternalFaces"
• -patches wordRes — add exposed internal faces to the closest of the specified patches instead of "oldInternalFaces"
• -region name — specify an alternative mesh region
• -resultTime time — specify a time for the resulting mesh ⏰
• -zone — subset with cellZone(s) instead of cellSet. the command argument may be a list of words or regexs, iykyk
• -doc — display documentation in browser
• -help — display short help and exit
• -help-full — display full help and exit

---

🌈 ADVANCED OPTIONS 🌈

• -debug-switch name=val — specify the value of a registered debug switch. default is 1 if the value is omitted. (can be used multiple times)
• -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. [Parallel option]
• -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)
• -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]
• -doc-source — display source code in browser
• -help-compat — display compatibility options and exit
• -help-man — display full help (manpage format) and exit
• -help-notes — display help notes (description) and exit

---

🧚 COMPATIBILITY OPTIONS 🧚

• -noFunctionObjects — okay so... this option is ignored. literally does nothing. she's just standing there. 💀

so yeah, that's the whole thing, bestie — go forth and subset that mesh, you absolute main character 👑
