SYRTHES-PP(1)

✨ SYRTHES-PP ✨

okay so bestie, gather round, because this is the manual page for syrthes-pp from the General Commands Manual section (section 1, obvs), and honestly? it's giving "tiny tool, huge job". let's get into it 💅

🌸 NAME 🌸

syrthes-pp — the pre-processor for the SYRTHES parallel version. it does the prep work before the parallel era begins, no cap.

🦋 SYNOPSIS 🦋

syrthes-pp [-h] ( -n nb_part | -e nb_elt ) -m maillage [-o
maillage_decoupe]

so like, you have to give it either -n or -e (pick a lane, babe — it's one or the other), and -m is literally non-negotiable. the -o is just vibes-optional but you'll want it, trust.

💖 DESCRIPTION 💖

it splits the initial mesh of a SYRTHES case, setting everything up so you can go do parallel processing later. it's the "getting ready" montage of your simulation. main character energy fr fr ✨

🎀 OPTIONS 🎀

• -h — help. the classic. she's always there for you 🫶
• -v — makes an Ensight ASCII vizualisation file with the partitions, so you can see the girlies you just created.
• -b — same idea but it's an Ensight gold vizualisation file with the partitions. fancy version, we love her 👑
• -n nb_part — how many partitions you wanna create. nb_part = the count, bestie.
• -e nb_elt — the maximum number of elements per partition. nb_elt is your cap, periodt.
• -l number — reads that many 'domain' files. so number of them, exactly.
• -f prefixe — the prefix of the files, as in dom.1 dom.2 dom.3 ... — you see the pattern, right? 🍓
• -m mesh — name of the initial mesh file (it's a .syr, iykyk).
• -o nompart — prefix of the destination files. where the chopped-up pieces get written.
• -d syrthes_data.syd — name of the SYRTHES data file. only needed if your calculation needs periodicity or contact resistances — otherwise skip it, she's not required.
• --toolpart metis — mesh partitioning thanks to METIS 5.
• --toolpart scotch — mesh partitioning thanks to SCOTCH. and heads up, this one is the default.

ngl, if you don't pass --toolpart at all, you're getting SCOTCH. no cap.

🌈 EXAMPLES 🌈

here's how the girlies actually run it:

pp_syrthes -n 3 -m carre.syr -o carre

or, if you're feeling spicy and you need that data file:

pp_syrthes -n 3 -m carre.syr -d syrthes.data -o carre

and the results? absolutely ate:

carre_00003part00000.syr
carre_00003part00001.syr
carre_00003part00002.syr

three partitions, three files, zero notes. iconic. 🔥

okay that's the whole page bestie, go partition something, love u bye 🎀💖
