Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.01138 |
| Opus 5 | $0.00019 | $0.00569 |
| Sonnet 5 | $0.00008 | $0.00228 |
| Haiku 4.5 | $0.00004 | $0.00114 |
Grade A, and why
abaqus-dynamic-analysis 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 10d 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 Dynamic Analysis Skill
This skill handles explicit and implicit dynamics for impact, crash, drop test, and transient response analysis.
When to Use This Skill
Route here when user mentions:
- Impact, crash, collision, drop test
- Transient response, time-varying response
- Shock loading, blast loading, explosive loading
- High-speed events, wave propagation
- "What happens when it hits..."
Route elsewhere:
- Natural frequency extraction →
/abaqus-modal-analysis - Static/constant loads →
/abaqus-static-analysis - Harmonic/sinusoidal response → modal + steady-state dynamics
- Very long transients (minutes+) → consider implicit or quasi-static
Prerequisites
Before dynamic analysis:
- Geometry and mesh ready
- Material MUST have density defined (required for mass matrix)
- Understand event duration and loading type
Workflow: Setting Up Dynamic Analysis
Step 1: Gather Information from User
Ask if unclear:
- What's the event duration? Milliseconds, seconds, or longer?
- Initial velocity? For drop tests or impact
- Is contact involved? Parts colliding or touching
- What output needed? Stress, velocity, acceleration, energy?
Step 2: Choose Explicit vs Implicit
| Factor | Explicit | Implicit |
|---|---|---|
| Time scale | Short (us to ms) | Longer (ms to s) |
| Step size | Automatic (very small) | User-controlled |
| Nonlinearity | Handles well | May need iterations |
| Memory | Lower | Higher |
| Contact | Natural handling | Needs care |
| Best for | Impact, crash | Vibration, long transient |
Decision rule:
- Event < 10ms with impact/contact → Explicit
- Event > 100ms without severe nonlinearity → Implicit
- In between → Either can work, explicit often easier
Step 3: Set Time Period
| Event Type | Typical Duration |
|---|---|
| High-speed impact | 0.1-10 ms |
| Drop test | 1-100 ms |
| Blast loading | 1-50 ms |
| Seismic/vibration | 1-100 s |
What ships with it
3 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.
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-dynamic-analysis is a skill published in the GitHub repository Cai-aa/CAE-Agent-Hub (859 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 1,138 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.
