🦋 mcv(1) — mesh file converter 🦋

okay bestie, welcome to the Scotch user's manual, section 1, where we meet mcv(1) — literally your little mesh-file glow-up machine. ✨ no cap, she converts, she slays, she does it all.

🌸 NAME 🌸

mcv — mesh file converter

💅 SYNOPSIS 💅

mcv [options] [imfile] [omfile] [oxfile]

✨ DESCRIPTION ✨

The mcv program converts Scotch mesh files from and to other external file formats. it's giving bilingual, but for meshes 💖

File imfile gets converted into mesh file omfile, with optional geometry data being dropped into geometry file oxfile — but only if it is available. like, if the geometry's not there, she's not gonna manifest it, bestie 🫶

When file names are not specified, data is read from standard input and written to standard output. Standard streams can also be explicitly represented by a dash '-'. yes, a whole single dash. iconic behavior honestly 💅

When the proper libraries have been included at compile time, mcv can directly handle compressed meshes, both as input and output. A stream is treated as compressed whenever its name is postfixed with a compressed file extension, such as in 'brol.msh.bz2' or '-.gz'. The compression formats which can be supported are:

  • the bzip2 format ('.bz2')
  • the gzip format ('.gz')
  • the lzma format ('.lzma')

no unzipping first, no notes, she just gets it 😌

⚠️ heads up: compressed input/output only works when those libraries were baked in at compile time. otherwise it's a vibe check she will fail.

👑 OPTIONS 👑

  • -h — Display some help. your girl is always down to help a bestie out 🥰
  • -iifmt — Set format of input mesh file, which can be:
    • bnum — Boeing-Harwell format. This is an elemental matrix format. Only square matrices are supported. In case the file contains several matrices, the num parameter allow the user to provide the index of the matrix to convert, starting from 0. When the num parameter is not set, it is assumed to be 0. so basically num is your "which one??" selector 🔢
    • s — Scotch mesh format.
  • -oofmt — Set format of output mesh file, which can be:
    • s — Scotch mesh format. This is the only possible choice at the time being. periodt. there is literally no other option and that's just how it is 💀
  • -V — Display program version and copyright. flex on 'em with the receipts 📜

🍓 EXAMPLE 🍓

Convert a Harwell-Boeing elemental mesh into a Scotch mesh.

$ mcv -ib brol.hb brol.msh

see? one line. she ate and left no crumbs 🔥
