🌸 NAME 🌸

elk-lapw — it's an all-electron full-potential linearised augmented-plane wave code. yes that's a whole mouthful, and yes it's iconic 👑

🦋 SYNOPSIS 🦋

elk-lapw

that's it. that's the whole synopsis. no flags, no args, just vibes ✨

💜 DESCRIPTION 💜

so elk-lapw is an all-electron full-potential linearised augmented-plane wave (FP-LAPW) code, and its whole thing is figuring out the properties of crystalline solids. and not in a basic way either — it comes with many advanced features 💅. she's versatile, she's thorough, she's that girl.

🎀 OPTIONS 🎀

ngl this part is gonna be quick:

  • literally none — the program has no options to use. zero. none. periodt. 💀

not me checking the options section and finding it empty 🙈. she takes no flags and she doesn't need them.

🌈 FILES 🌈

okay this is the part where the file naming conventions are genuinely so satisfying, lowkey obsessed 🫶

  • all input files for the code are in lower case and end with the extension .in
  • all output files are UPPERCASE and have the extension .OUT

the input file is elk.in, and it contains all parameters, arranged in blocks 🧱. if you wanna know more about the file format, you gotta refer to the official documentation. iykyk 📚

lowercase in, UPPERCASE out. it's giving organized. it's giving she has a system and she sticks to it. 👑

🌸 ENVIRONMENT 🌸

elk-lapw was compiled with OpenMP and MPI enabled 🔥. which means — and this is the fun part — you can use all the environmental variables those libraries provide. that's the whole vibe. go wild, bestie, the libraries got you 🌈

🦋 AUTHORS 🦋

this manual page was written by Daniel Leidert <daniel.leidert@wgdd.de> for the Debian system (but it may be used by others too, so no gatekeeping 💖).

and that's the whole page, babe 💅 thanks for reading all the way through, you ate that fr fr 🍓✨
