✨ BLOCKMESH(1) ✨

okay so bestie, meet blockMesh — she's part of OpenFOAM (The Open Source CFD Toolbox), and she is literally the moment. 💅

🌸 SYNOPSIS 🌸

blockMesh [OPTIONS]

🦋 DESCRIPTION 🦋

Block mesh generator. 🎀 That's her whole thing. She makes blocks, she meshes them, she serves.

So here's the tea on how vertex and face labels get ordered inside a block — for the local vertex numbering in the sequence 0 to 7:

  • Faces 0, 1 (x-direction) are left, right.
  • Faces 2, 3 (y-direction) are front, back.
  • Faces 4, 5 (z-direction) are bottom, top.

And the visual, because iykyk, you NEED the visual:

                               7 ---- 6
                        f5     |\     |\     f3
                        |      | 4 ---- 5     \
                        |      3 |--- 2 |      \
                        |       \|     \|      f2
                        f4       0 ---- 1
           Y  Z
            \ |                f0 ------ f1
             \|
              O--- X

  • -dict file — Alternative dictionary for the blockMesh description. swap in a different file, go off.
  • -noClean — Do not remove any existing polyMesh/ directory or files. she leaves everything exactly where it was. no cleanup era. 🙈
  • -region name — Specify alternative mesh region.
  • -sets — Write cellZones as cellSets too (for processing purposes). double duty, she contains multitudes. ✨
  • -time time — Specify a time to write mesh to (default: constant).
  • -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.
  • -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)
