VMTKMESHARRAYOPERATION(1)

💖 VMTKMESHARRAYOPERATION 💖

okay bestie, so this is vmtkmesharrayoperation, a User Command from the vmtk fam (that's the Vascular Modeling Toolkit, iykyk) ✨

---

🌸 NAME 🌸

vmtkmesharrayoperation — literally the vmtk script vmtkmesharrayoperation, no cap 🫶

---

✨ DESCRIPTION ✨

So the vibe here is: automatic piping, vmtkmesharrayoperation parsing options, vmtkmesharrayoperation. That's the boilerplate, she's just doing her little intro dance 💅

Now for the real tea, this is what she does:

vmtkmesharrayoperation : perform an operation between arrays of two

meshes and store result in the first mesh

Bestie. She takes an array from mesh one, an array from mesh two, does math on them, and drops the result right back into the first mesh. Main character energy fr fr 👑

---

🎀 Input arguments:

• -id Id (str,1); default=0 — the script id, it's giving serial number energy
• -handle Self (self,1) — handle to self, she's holding up a mirror 🪞
• -disabled Disabled (bool,1); default=0 — turns off execution and piping, like do-not-disturb mode 🙈
• -i Mesh (vtkUnstructuredGrid,1) — the input mesh, aka the first one, aka the one that gets the result at the end 👑
• -ifile MeshInputFileName (str,1) — filename for the default Mesh reader, so she knows where to read from 📂
• -i2 Mesh2 (vtkUnstructuredGrid,1) — the second input mesh, the other one, the supporting actress 💜
• -i2file Mesh2InputFileName (str,1) — filename for the default Mesh2 reader, for mesh two obviously 📂
• -operation Operation (str,1) in ['multiplybyc', 'addc', 'add', 'subtract', 'min', 'max']; default=add — the operation to be performed on the array. heads up: multiplybyc and addc only require the first input mesh to be specified, so you can skip the second one, slay ✨
• -constant Constant (float,1); default=0.0 — the value of the constant for multiplybyc and addc, aka the little number she's multiplying by or adding 🍓
• -iarray InputArrayName (str,1); default=None — the name of the array on the first mesh, you gotta tell her which one 🎯
• -i2array Input2ArrayName (str,1); default=None — the name of the array on the second mesh; if unspecified, InputArrayName is used. yes bestie, she reuses the first name by default, convenience queen 💅
• -resultarray ResultArrayName (str,1); default=Result — the name of the array where the result of the operation is stored. it literally defaults to Result, iconic, no notes 🌈
• -ofile MeshOutputFileName (str,1) — filename for the default Mesh writer, where it all goes at the end 📝

---

💜 Output arguments:

• -id Id (str,1); default=0 — the script id again, yes she says it twice, she contains multitudes
• -handle Self (self,1) — handle to self, again, still her 🪞
• -o Mesh (vtkUnstructuredGrid,1) — the output mesh, the final product, the glow-up ✨

ngl the -id and -handle showing up in both input and output arg lists is a whole thing, but that's just how the piping works, don't come for her 💀

---

okay that's the whole page bestie, every single flag accounted for, nothing skipped, we ate and left no crumbs 🍽️💖

this was vmtk script version 1.5, dated April 2026, mwah, kisses, go run it 🌸🦋🎀
