💖 NAME 💖

okay bestie so mkgeo_sector — it makes you a mesh of a sector ✨ that's the whole vibe, and it's from rheolef-7.2. periodt.

🦋 SYNOPSIS 🦋

mkgeo_sector [options] n

🌸 EXAMPLE 🌸

so like, this command right here builds a 2d unstructured mesh of the triangular region that's delimited by the three points (0,0), (1,0), (1,1) — iconic little triangle fr:

mkgeo_sector
geo sector.geo

✨ DESCRIPTION ✨

this command is lowkey the moment when you need a mesh for a sector of a square pipe section, because that is literally a very classical benchmark in complex fluid flow problems 🫶 iykyk.

it calls the bamg unstructured mesh generator for you, no cap. the mesh files go on name.geo, where name is the basename for the output — peep the option -name below for that 💅.

and the three auxiliary files that you need for automatic mesh generation with Rheolef combined with bamg? they're also provided, bestie:

name.bamg
name.bamgcad
name.dmn

🎀 THE GEOMETRY 🎀

the geometry is the triangular sector (0,0), (a,0), (a,b). by default a=b=1 — cute, symmetrical, we love that.

  • -a float
  • -b float

these options control the geometry parameters 💖

💜 THE DISCRETIZATION 💜

the optional n argument is an integer that specifies the subdivision in each direction. by default n=10 — so if you don't say anything, you get 10. main character default energy honestly.

🌈 BOUNDARY DOMAINS 🌈

the boundary sides are represented by domains, and there are three of them: axis, boundary, and bisector 🧚

💅 OTHERS OPTIONS 💅

  • -name string — sets the basename for the output files. by default the basename is sector (adorable).
  • -[no]clean — clears the temporary files. and yes bestie, this is the default ✨
  • -[no]verbose — in verbose mode, it prints to stderr all commands and logs. it's giving very chatty, very transparent 🔥

🔥 IMPLEMENTATION 🔥

this documentation has been generated from file main/sbin/mkgeo_sector.sh — that's the source of truth, no guessing 💀
