Generate finite element meshes. An agent skill from Cai-aa/CAE-Agent-Hub.
- Works in 6 steps: Understand User's Goal → Choose Element Type → Choose Mesh Size → …
- User mentions mesh
- SKILL.md covers When to Use This Skill, Prerequisites, Workflow: Generating a Mesh and Element Type Reference, plus 3 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Abaqus Mesh is an agent skill from Cai-aa/CAE-Agent-Hub. Generate finite element meshes. Use when user mentions mesh, elements, nodes, refine mesh, mesh size, or asks about element types like C3D8R, C3D10, S4R.
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 Research & Science, covering Physical and earth sciences. The licence is MIT.
When your agent uses it
- User mentions mesh
- Asks about element types like C3D8R
Example prompts
- “/abaqus-mesh”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(abaqus:*)
Workflow steps
6 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 Mesh loads about 1.2k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 526 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 Mesh Skill
Generate finite element meshes for Abaqus models. Discretizes geometry into elements and nodes for analysis.
When to Use This Skill
Route here when user mentions:
- "Mesh the part", "generate mesh"
- "Element size", "mesh size", "refine mesh"
- "Element type", "C3D8R", "C3D10", "S4R"
- "Too many nodes", "Learning Edition limit"
- "Mesh quality", "check elements"
Route elsewhere:
- Creating or modifying geometry →
/abaqus-geometry - Creating partitions for loads/BCs →
/abaqus-geometry - Extracting mesh-based results →
/abaqus-odb
Prerequisites
Before meshing:
- Geometry must be complete
- Sections should be assigned (material assignment)
Workflow: Generating a Mesh
Step 1: Understand User's Goal
Ask if unclear:
- Target mesh size? Coarse (fast) or fine (accurate)?
- Hex or tet elements? Simple geometry → hex; complex → tet
- Local refinement? Stress concentrations need finer mesh
Step 2: Choose Element Type
| Geometry | Recommended | Code | Notes |
|---|---|---|---|
| Simple box/prism | Hex, reduced | C3D8R | Fast, accurate, try first |
| Complex freeform | Tet, quadratic | C3D10 | Meshes anything |
| Thin-walled (t/L < 0.1) | Shell | S4R | Plates, shells |
| Slender beams (L/d > 10) | Beam | B31 | Frames, trusses |
Decision guidance:
- Can it be hex-meshed? → Try C3D8R first
- Complex shape or holes? → Use C3D10 (tet)
- Thin structure? → Use S4R shell
- Explicit dynamics? → C3D8R works well
Step 3: Choose Mesh Size
| Use Case | Element Size | Guideline |
|---|---|---|
| Quick feasibility | 10-20mm | 5+ elements across model |
| General analysis | 3-5mm | 10+ elements across smallest dimension |
| Stress concentrations | 1-2mm | 5+ elements in high-gradient regions |
| Topology optimization | 2-5mm | 3-5 elements across expected members |
Rule of thumb: At least 3 elements across any feature you care about.
Step 4: Check Learning Edition Limits
Learning Edition allows max 1000 nodes.
| Box Dimensions (mm) | Max Element Size |
|---|---|
| 100 x 100 x 100 | 20mm |
| 100 x 50 x 30 | 10mm |
| 50 x 50 x 50 | 12mm |
| 200 x 100 x 50 | 25mm |
Estimation formula: nodes ≈ (L/size + 1) × (W/size + 1) × (H/size + 1)
Step 5: Apply Local Refinement (If Needed)
Refine mesh near:
- Holes and notches (stress concentrations)
- Fillets and sharp corners
- Load/BC application points
Options:
- Edge seeds with smaller size
- Edge seeds with specific element count
- Biased mesh (graded density)

Step 6: Generate and Verify
After mesh generation, check:
- Node count within limits
- Element count reasonable
- No mesh quality warnings
- Elements exist in all regions
Element Type Reference
3D Solid Elements
| Code | Type | Nodes | Use Case |
|---|---|---|---|
| C3D8R | Hex, reduced | 8 | General purpose (recommended) |
| C3D8 | Hex, full | 8 | Bending-dominated, no hourglass |
| C3D20R | Hex, quadratic | 20 | High accuracy, expensive |
| C3D4 | Tet, linear | 4 | Complex geometry (less accurate) |
| C3D10 | Tet, quadratic | 10 | Complex geometry (better accuracy) |
Shell Elements
| Code | Type | Nodes | Use Case |
|---|---|---|---|
| S4R | Quad, reduced | 4 | General purpose (recommended) |
| S4 | Quad, full | 4 | No hourglass |
| S3 | Triangle | 3 | Complex surfaces |
Mesh Quality Guidelines
| Metric | Target | Warning | Failure |
|---|---|---|---|
| Aspect ratio | < 5:1 | 5-10:1 | > 10:1 |
| Jacobian | > 0.5 | 0.1-0.5 | < 0.1 |
| Min angle (quad) | > 45° | 30-45° | < 30° |
Troubleshooting
| Problem | Likely Cause | Solution |
|---|---|---|
| "Cannot mesh region" | Geometry too complex for hex | Switch to TET with FREE technique |
| "Element distortion" | Poor element shapes | Refine locally or fix geometry |
| "Exceeded node limit" | Mesh too fine | Increase element size |
| "No mesh controls" | Missing mesh technique | Set mesh controls before generating |
| Mesh won't generate | Gaps in geometry | Check geometry, merge if needed |
