VMTKMESHMERGETIMESTEPS(1)

✨ NAME ✨

vmtkmeshmergetimesteps — the vmtk script called vmtkmeshmergetimesteps, and she is here to merge multiple mesh files with different timesteps into one 🦋

---

💖 DESCRIPTION 💖

okay so bestie, real talk: this page opens with Automatic piping vmtkmeshmergetimesteps Parsing options vmtkmeshmergetimesteps — that's literally what it says, I'm not gatekeeping anything from you 🫶

then the actual vibe check:

vmtkmeshmergetimesteps : merge multiple mesh files with different
       timesteps into one

🎀 Input arguments 🎀

yes she takes a lot of them. no we are not skipping any. every single one, periodt 💅

• -id — Id (str,1); default=0: script id. her little name tag, lowkey.
• -handle — Self (self,1): handle to self. no default, she's just there, main character energy.
• -disabled — Disabled (bool,1); default=0: disable execution and piping. turn it on and she simply stops. iconic.
• -directory — InputDirectoryName (str,1); default=None
• -pattern — Pattern (str,1); default=None
• -firststep — FirstTimeStep (int,1) >= 0; default=None
• -laststep — LastTimeStep (int,1) >= 0; default=None
• -intervalstep — IntervalTimeStep (int,1) >= 0; default=1
• -components — VelocityComponentsArrayNames (str,-1); default=u v w
• -velocityvector — VelocityVector (bool,1); default=0: velocity vector instead of components
• -vector — VelocityVectorArrayName (str,1); default=None: velocity vector name
• -pressure — Pressure (bool,1); default=0: pressure array
• -pressurearrayname — PressureArrayName (str,1); default=p: name of the pressure array
• -wallshearrate — Wsr (bool,1); default=0: wallshearrate array
• -components — WsrComponentsArrayNames (str,-1); default=taux tauy tauz
• -wsrvector — WsrVector (bool,1); default=0: wallshearrate vector instead of components
• -ofile — MeshOutputFileName (str,1): filename for the default Mesh writer

not me noticing -components shows up twice in that list 👀 one for VelocityComponentsArrayNames and one for WsrComponentsArrayNames — that's exactly how the page lists them, so that's how I'm listing them, no editing, no merging, no cap.

It's giving int flags with >= 0 constraints and None defaults for days, honestly. obsessed.

👑 Output arguments 👑

• -id — Id (str,1); default=0: script id
• -handle — Self (self,1): handle to self
• -o — Mesh (vtkUnstructuredGrid,1): the output mesh. the whole reason we're here fr fr ✨

heads up bestie: those option lines are written exactly as the page gives them — types, defaults, everything. I did not touch a character. 🧚

💜 that's the whole page. she's version 1.5, dated April 2026, and that's the tea. bye bestie, go merge those timesteps 🔥💖
