At a glance

Complete workflow for dynamic analysis. An agent skill from Cai-aa/CAE-Agent-Hub.

  • Works in 7 steps: Gather Information from User → Choose Explicit vs Implicit → Set Time Period → …
  • User mentions impact
  • SKILL.md covers When to Use This Skill, Prerequisites, Workflow: Setting Up Dynamic… and Key Parameters, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Abaqus Dynamic Analysis is an agent skill from Cai-aa/CAE-Agent-Hub. Complete workflow for dynamic analysis. Use when user mentions impact, crash, drop test, transient, or time-varying response. Handles explicit and implicit dynamics.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `UPSTREAM.md` and `metadata.json`).

The licence is MIT.

When your agent uses it

  • User mentions impact
  • Time-varying response

Example prompts

  • “/abaqus-dynamic-analysis”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(abaqus:*), Skill

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Gather Information from User
  2. Choose Explicit vs Implicit
  3. Set Time Period
  4. Define Initial Conditions
  5. Configure Output
  6. Consider Mass Scaling (Explicit Only)
  7. Run and Validate

What it can do on your machine

Read from SKILL.md and the folder at commit 194ef49. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Glob
    • Grep
    • Bash(abaqus:*)
    • Skill

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Abaqus Dynamic Analysis loads about 1.2k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 504 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

  1. Geometry and mesh ready
  2. Material MUST have density defined (required for mass matrix)
  3. 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
FactorExplicitImplicit
Time scaleShort (us to ms)Longer (ms to s)
Step sizeAutomatic (very small)User-controlled
NonlinearityHandles wellMay need iterations
MemoryLowerHigher
ContactNatural handlingNeeds care
Best forImpact, crashVibration, 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 TypeTypical Duration
High-speed impact0.1-10 ms
Drop test1-100 ms
Blast loading1-50 ms
Seismic/vibration1-100 s
Step 4: Define Initial Conditions

For drop tests and impact:

  • Set initial velocity on the impacting part/region
  • Velocity is applied in the Initial step
Step 5: Configure Output

Field outputs: S (stress), U (displacement), V (velocity), A (acceleration), PEEQ (plastic strain)

History outputs for energy balance (explicit): ALLKE, ALLIE, ALLWK, ETOTAL

Show full SKILL.md (217 more words)Show less
Step 6: Consider Mass Scaling (Explicit Only)
OptionEffectWhen
NoneTrue inertiaVery short events, accuracy critical
At beginningScale onceQuasi-static explicit
ThroughoutContinuous scalingWhen inertia less important

Warning: Mass scaling speeds up analysis but affects inertial response.

Step 7: Run and Validate

Use /abaqus-job to submit, then check:

  • Energy balance (ETOTAL approximately constant)
  • Stable time increment (explicit)
  • Results physically reasonable

Key Parameters

ParameterExplicitImplicit
Time periodEvent durationEvent duration
Time incrementAutomaticSpecify initial, min, max
Element libraryEXPLICITSTANDARD
Element typeC3D8R recommendedC3D8R or C3D8
Hourglass controlENHANCEDDefault

Validation Checklist

  • Density defined in material
  • Time period appropriate for event
  • Initial conditions applied (velocity, position)
  • Output frequency captures behavior (100+ frames typical)
  • Energy balance acceptable (ETOTAL constant for explicit)
  • Results physically reasonable

Troubleshooting

ProblemLikely CauseSolution
"Time increment too small"Small/distorted elementsUse mass scaling or coarsen mesh
Energy balance errorHourglass or instabilityCheck hourglass energy, add control
Analysis takes forever (explicit)Long time periodConsider implicit instead
Convergence failure (implicit)Severe nonlinearityUse explicit or smaller increments
  • /abaqus-material - Define density (required)
  • /abaqus-amplitude - Time-varying loads
  • /abaqus-field - Initial velocity and predefined fields
  • /abaqus-interaction - Contact for impact problems
  • /abaqus-odb - Results extraction
