mesh-generation

mesh-generation is a skill for Claude Code from beita6969/ScienceClaw. It costs 40 tokens per session (1,202 once invoked), scanned A, original, MIT.

A guide for planning the computational grid, or mesh, used to solve partial differential equations in numerical simulations. It covers resolution, element shape, skewness, aspect ratios, mesh types, and adaptive refinement.

In plain words
What is it for?
Use it to choose structured, unstructured, hybrid, or adaptive meshes and to estimate resolution requirements for simulation domains.
Why use it?
A poorly chosen mesh can miss important physical features or make a simulation unreliable. This helps connect the smallest feature in the problem with suitable grid spacing and quality limits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mesh-generation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/grid_sizing.py, scripts/mesh_quality.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Mesh Generation

Goal

Provide a consistent workflow for selecting mesh resolution and checking mesh quality for PDE simulations.

Requirements

  • Python 3.8+
  • No external dependencies (uses stdlib)

Inputs to Gather

Input Description Example
Domain size Physical dimensions 1.0 × 1.0 m
Feature size Smallest feature to resolve 0.01 m
Points per feature Resolution requirement 10 points
Aspect ratio limit Maximum dx/dy ratio 5:1
Quality threshold Skewness limit < 0.8

Decision Guidance

Resolution Selection

What is the smallest feature size?
├── Interface width → dx ≤ width / 5
├── Boundary layer → dx ≤ layer_thickness / 10
├── Wave length → dx ≤ lambda / 20
└── Diffusion length → dx ≤ sqrt(D × dt) / 2

Mesh Type Selection

Problem Recommended Mesh
Simple geometry, uniform Structured Cartesian
Complex geometry Unstructured triangular/tetrahedral
Boundary layers Hybrid (structured near walls)
Adaptive refinement Quadtree/Octree or AMR

Script Outputs (JSON Fields)

Script Key Outputs
scripts/grid_sizing.py dx, nx, ny, nz, notes
scripts/mesh_quality.py aspect_ratio, skewness, quality_flags

Workflow

  1. Estimate resolution - From physics scales
  2. Compute grid sizing - Run scripts/grid_sizing.py
  3. Check quality metrics - Run scripts/mesh_quality.py
  4. Adjust if needed - Fix aspect ratios, reduce skewness
  5. Validate - Mesh convergence study

Conversational Workflow Example

User: I need to mesh a 1mm × 1mm domain for a phase-field simulation with interface width of 10 μm.

Agent workflow:

  1. Compute grid sizing:
    python3 scripts/grid_sizing.py --length 0.001 --resolution 200 --json
    
  2. Verify interface is resolved: dx = 5 μm, interface width = 10 μm → 2 points per interface width.
  3. Recommend: Increase to 500 points (dx = 2 μm) for 5 points across interface.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mesh-generation is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It adds 40 tokens to every session and 1,202 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
