What it does
Abaqus Step is an agent skill from Cai-aa/CAE-Agent-Hub. Define analysis steps and procedures. Use when user mentions static analysis, dynamic step, frequency analysis, heat transfer step, or asks about analysis type, time increments, or nlgeom.
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`).
It sits in Security, covering Static analysis and SAST. The licence is MIT.
When your agent uses it
- User mentions static analysis
- Frequency analysis
- Heat transfer step
- Asks about analysis type
Example prompts
- “/abaqus-step”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(abaqus:*)
Workflow steps
5 steps, taken from the step headings in SKILL.md.
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:
ReadWriteEditGlobGrepBash(abaqus:*)
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 Step loads about 1.2k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 483 words of instructions outside code blocks.
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 Step Skill

- "analysis type", "time increments", "nlgeom"
- "convergence issues", "increment size", "time step"
- "multi-step analysis", "sequential loading"

Workflow: Creating Analysis Steps
Step 1: Understand User's Physics
Ask if unclear:
- What physics? Stress, vibration, heat transfer, coupled?
- Static or dynamic? Constant load vs time-varying?
- Linear or nonlinear? Small or large deformations?
Step 2: Choose Step Type
| Analysis Goal | Step Type | Key Parameter |
|---|---|---|
| Stress under constant load | StaticStep | nlgeom=OFF/ON |
| Natural frequencies | FrequencyStep | numEigen |
| Buckling modes | BuckleStep | numEigen |
| Transient dynamics (smooth) | ImplicitDynamicsStep | timePeriod |
| Impact/crash | ExplicitDynamicsStep | timePeriod |
| Heat conduction | HeatTransferStep | response |
| Thermal + structural | CoupledTempDisplacementStep | timePeriod |
| Harmonic response | SteadyStateDynamicsStep | frequencyRange |
Most common: StaticStep with nlgeom=OFF for linear stress analysis.
Step 3: Determine Linearity
| Condition | nlgeom Setting | When |
|---|---|---|
| Small deformation, linear material | OFF | Default, fastest |
| Large rotation/displacement | ON | Thin structures, cables |
| Plasticity | ON | Material yields |
| Contact | ON | Parts touching |
| Buckling | ON | Post-buckling behavior |
Step 4: Configure Increment Control
| Convergence Difficulty | initialInc | minInc | maxInc |
|---|---|---|---|
| Easy (linear) | 1.0 | 1e-6 | 1.0 |
| Moderate | 0.1 | 1e-8 | 0.2 |
| Difficult (contact, plasticity) | 0.01 | 1e-12 | 0.05 |
Step 5: Chain Multiple Steps (if needed)
For sequential loading:
- First step uses
previous='Initial' - Subsequent steps chain from previous step name
- Each step can have different physics or settings
Key Parameters
| Parameter | Purpose | Typical Value |
|---|---|---|
| timePeriod | Duration of step | 1.0 for static |
| initialInc | Starting increment size | 0.1 for nonlinear |
| maxNumInc | Maximum iterations | 100 |
| minInc | Smallest allowed increment | 1e-8 |
| maxInc | Largest allowed increment | 0.1-1.0 |
| numEigen | Modes to extract | 10 |
| deltmx | Max temp change per increment | 5.0-10.0 |

Special Considerations
Frequency/Modal Analysis
- Always from Initial step (no preload needed for basic modal)
- Use LANCZOS eigensolver for large models
- Extract 10-20 modes typically
Buckling Analysis
- Usually follows a load step (to apply reference load)
- Eigenvalues are load multipliers
- First positive eigenvalue is critical
Explicit Dynamics
- Time period should be very short (milliseconds)
- Increment size determined automatically
- Mass scaling may be needed for quasi-static problems
Heat Transfer
- STEADY_STATE for equilibrium temperature
- TRANSIENT for time-varying temperature
- deltmx controls accuracy vs speed
Troubleshooting
| Problem | Likely Cause | Solution |
|---|---|---|
| "Too many increments" | Convergence difficulty | Reduce maxInc, increase maxNumInc |
| "Negative eigenvalues" | Unconstrained or unstable | Check BCs, add stabilization |
| "Time increment too small" | Severe nonlinearity | Add stabilization, check material |
| "Explicit time increment" | Very small elements | Use mass scaling or coarsen mesh |
Validation Checklist
After step creation, verify:
- Step type matches analysis physics
- nlgeom setting appropriate for deformation level
- Increment control parameters reasonable
- Step chains correctly from previous
- Time period appropriate for transient analysis
