abaqus-shape-optimization

abaqus-shape-optimization is a skill for Claude Code from Cai-aa/CAE-Agent-Hub. It costs 38 tokens per session (1,079 once invoked), scanned A, original, MIT.

A guide for changing existing surfaces in an Abaqus model to reduce areas where stress becomes concentrated. It is suited to refining shapes such as fillets and notches without adding or removing material.

In plain words
What is it for?
Use it to optimize fillet sizes, reshape surfaces, smooth geometry, reduce peak stress, or improve fatigue life.
Why use it?
It helps improve a known design with local stress problems while keeping its basic material layout.

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

abaqus-shape-optimization 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 7d ago.

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.

Abaqus Shape Optimization Skill

Optimize surface geometry to reduce stress concentrations. Shape optimization moves existing surfaces without adding or removing material.

When to Use This Skill

Route here when user mentions:

  • "stress concentration", "reduce peak stress"
  • "fillet optimization", "optimize fillet radius"
  • "reshape surface", "smooth geometry"
  • "improve fatigue life", "notch optimization"

Route elsewhere:

  • Adding/removing material (holes, organic forms) → /abaqus-topology-optimization
  • Low-level optimization setup → /abaqus-optimization
  • Running the optimization job → /abaqus-job

Shape vs Topology Optimization

Aspect Shape Optimization Topology Optimization
What changes Surface positions Material presence
Result Smooth surfaces Holes, organic forms
Manufacturing Traditional machining Often needs AM/casting
Design freedom Limited High
Best for Refine existing design Conceptual design

Rule of thumb: Use shape optimization when you have a good design with local stress issues. Use topology when starting fresh or need major redesign.

Prerequisites

Before shape optimization:

  1. ✅ Working static analysis that converges
  2. ✅ Identified high-stress surface region
  3. ✅ Full Abaqus license with Tosca (not Learning Edition)

Workflow: Shape Optimization

Step 1: Run Baseline Analysis

Run static analysis to identify stress concentrations. Note peak stress location and magnitude for comparison baseline.

Step 2: Identify Design Surfaces

Ask user if unclear: Which surfaces can be modified? Which must remain fixed?

Only select surfaces that can be modified in manufacturing, are not functional interfaces, and don't have attached features.

Step 3: Define Movement Limits

Get maximum growth/shrink (mm). Typical values: 3-10mm depending on part size.

Step 4: Choose Objective

User Goal Objective Design Response
Reduce stress concentration MINIMIZE_MAXIMUM STRESS (MISES)
Uniform stress distribution MINIMIZE_MAXIMUM MAX_PRINCIPAL_STRESS
Maximize stiffness MINIMIZE_MAXIMUM STRAIN_ENERGY

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.

abaqus-shape-optimization is a skill published in the GitHub repository Cai-aa/CAE-Agent-Hub (839 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 1,079 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 2026-08-30.
