VMTKMESHWALLSHEARRATE(1)

💅 NAME 💅

vmtkmeshwallshearrate — it's a vmtk script, bestie, and its whole personality is computing the wall shear rate off a velocity field and handing you back a surface. That's it. That's the girl. 🩸✨

🌸 DESCRIPTION 🌸

Okay so first things first: vmtk does its little automatic piping thing, and then vmtkmeshwallshearrate starts parsing options. Yes, the manpage literally says that, and yes it's giving "the tutorial narration nobody asked for." 🫶

Here's the actual vibe: vmtkmeshwallshearrate computes wall shear rate from a velocity field, and it produces a surface in the output. Lowkey iconic of it tbh. 🦋

✨ Input arguments ✨

• -id Id (str,1); default=0 — the script id. Just the little name tag this script wears.
• -handle Self (self,1) — a handle to self. Yeah, it's holding its own hand. Main character behavior. 💅
• -disabled Disabled (bool,1); default=0 — flip this and execution and piping get disabled. Turning off the whole operation, no cap.
• -i Mesh (vtkUnstructuredGrid,1) — the input mesh. Your data girl goes here. 🎀
• -ifile MeshInputFileName (str,1) — the filename for the default Mesh reader, so the default reader knows where to go.
• -velocityarray VelocityArrayName (str,1); default=None — no default array name, so you do have to tell it which one. Not me letting you guess. 🙈
• -wsrarray WallShearRateArrayName (str,1); default=WallShearRate — the name for the wall shear rate array, and it defaults to WallShearRate. She came pre-named, periodt.
• -tolerance ConvergenceTolerance (float,1); default=1e-06 — the convergence tolerance. Tiny. Microscopic. A literal 1e-06. 💀
• -fulltensor UseFullStrainRateTensor (bool,1); default=0 — whether to use the full strain rate tensor. Off by default, so it's 0 unless you say otherwise.
• -quadratureorder QuadratureOrder (int,1); default=3 — the quadrature order, defaulting to 3. Math girlies rise. 🌈
• -ofile SurfaceOutputFileName (str,1) — filename for the default Surface writer, so your output surface has somewhere to land. 🍓

👑 Output arguments 👑

• -id Id (str,1); default=0 — the script id again. She's listed on both sides, and honestly? Balanced. ⭐
• -handle Self (self,1) — handle to self, once more, for the output side of the story.
• -o Surface (vtkPolyData,1) — the output surface. The whole point, the final look, the reveal. 🔥💜

And that's the whole page, bestie — no skips, no secrets, every flag accounted for. 🧚
