💖 EVOLVER-NOX-D(1) 💖

okay bestie, so this is evolver-nox-d, the Surface Evolver program — but the no-X-support, double-precision-floating-point-flavored one. she's from the Surface Evolver family and she's here to minimize energy, not to draw you pretty windows. periodt. ✨

🌸 SYNOPSIS 🌸

evolver-nox-d [-a][-d][-e][-i][-m][-q][-w][-x][-y][-h][-V] [-f FILE]
[-pN] [DATAFILE]

🦋 DESCRIPTION 🦋

The Surface Evolver is an interactive program for the modelling of liquid surfaces shaped by various forces and constraints. Basically — and I need you to hear me on this — the Surface Evolver minimizes the energy of triangulated surfaces according to designated energies and constraints. that's the whole vibe. 🫶

This man page mainly documents command line options and environment variables. (iykyk — the deep lore lives in the manual, not here.)

✨ OPTIONS ✨

  • -a — Autoconvert to named quantities when needed (default is on); use -a- to deactivate autoconversion.
  • -d — Begin with parser debugging on (equivalent to the debug runtime command); beware of copious output. not me flooding your terminal 💀
  • -e — Echo stdin to stdout; meant for testing piped input.
  • -f FILE — After loading DATAFILE, read commands from FILE, then command line prompt.
  • -i — Preserve DATAFILE numbers for element id's, rather than renumbering. keep the originals, they're iconic.
  • -m — Begin with memory debugging on (equivalent to the memdebug runtime command); beware of copious output. again: brace yourself 😭
  • -pN — Run with N concurrent processes. multitasking queen 👑
  • -q — Convert to named quantities at start (equivalent to the convert_to_quantities runtime command).
  • -w — Exit immediately after any warning or error message; meant for batch runs.
  • -x — Exit immediately after any error message; meant for batch runs.
  • -y — Break to user prompt after any warning message.
  • -h — Display this help, then exit. 🎀
  • -V — Display the version and the banner, then exit. 🌈

🧚 AVAILABILITY 🧚

The latest version of the Surface Evolver, up-to-date documentation, and more are available on-line from:

http://www.susqu.edu/brakke/evolver

Surface Evolver Version 2.70a (Debian 2.70+ds-10), August 27, 2013, 64-bit. Compiled for double, 15 digits precision. Built with Geomview support.

yes she's 64-bit. yes she's serving 15 digits of precision. no notes. 💅

💜 ENVIRONMENT 💜

  • EVOLVERPATH — Colon-separated list of paths automatically searched for datafiles, included files, or on-line help documentation. By default, the paths /usr/share/doc/evolver/html and /usr/share/doc/evolver/examples are appended (in that order); this default behaviour can be cancelled by appending at least three consecutive colons (":::") at its end.

🎀 FILES 🎀

  • ~/.evolver_history — Per user command history file. she remembers everything, lowkey 🙈
  • /usr/share/doc/evolver/manual.pdf — The (complete) Surface Evolver Manual in PDF format.
  • /usr/share/doc/evolver/EvolverDoc.html — The HTML version of the Surface Evolver Manual that contains what the PDF manual has, modulo some advanced material.
  • /usr/share/doc/evolver/examples/ — This folder contains sample material, mainly datafiles and command-files, for the Surface Evolver.
