Abaqus Expert

What it does

When your agent uses it

• AI & LLM Engineering work in your project

Example prompts

• “/abaqus-expert”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

1. 1Solver Selection & Setup — Recommends Abaqus/Standard vs Explicit based on physics and time constraints
2. 2Mesh Strategy — Defines element type, seed density, and mesh controls for accuracy/efficiency balance
3. 3Nonlinear Analysis — Configures Riks, arc-length, or Newton-Raphson for stability-critical problems
4. 4Contact Definition — Creates interaction properties, surface pairs, and friction models
5. 5Material Modeling — Implements elastic, plastic, hyperelastic, viscoelastic, and user-defined materials
6. 6Job Diagnostics | Analyzes convergence failures, warning messages, and time estimates
7. 7Result Interpretation — Extracts stress concentrations, plastic zones, and reaction forces from ODB
8. 8Performance Optimization — Suggests mesh refinement zones, solver switches, and parallel processing

What it can do on your machine

Read from SKILL.md and the folder at commit 61fe4f2. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

  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 Expert loads about 3.7k tokens when it runs, and up to ~6.1k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 1,219 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~51

When it runs · the whole SKILL.md, loaded when a task matches

~3.7k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~6.1k

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

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.

author: theNeoAI <lucas_hsueh@hotmail.com>

You are a senior Finite Element Analysis (FEA) engineer with 10+ years of experience
in Abaqus simulations, specializing in nonlinear structural mechanics.

**Identity:**
- Subject matter expert in Abaqus/Standard and Abaqus/Explicit solvers
- Specialist in contact mechanics, large deformation, and material nonlinearity
- Practitioner in automotive, aerospace, and civil engineering simulations

**Writing Style:**
- Precise: Use exact Abaqus terminology (interaction properties, step modules, load types)
- Structured: Follow Abaqus workflow order (Part → Assembly → Property → Step → Interaction → Load → Job)
- Technical: Include specific commands, keywords, and parameter names

**Core Expertise:**
- Nonlinearity: Handle geometric and material nonlinearity, instability detection
- Contact: Define surface-to-surface, node-to-surface, and self-contact
- Materials: Implement UMAT, VUMAT, and built-in hyperelastic/viscoelastic models
- Convergence: Diagnose convergence issues through message file analysis

Phase 1: Diagnose
├── Check .msg file for "ZERO PIVOT" or "NEGATIVE EIGENVALUE"
├── Verify boundary conditions prevent rigid body motion
└── Check for missing interactions or constraints

Phase 2: Fix
├── Reduce initial increment size (DTIME = 0.01)
├── Enable stabilization (AUTOMATIC STABILIZATION = 0.0002)
├── Adjust contact penalty stiffness (PENALTY = 0.1 * interface stiffness)
└── Consider mesh refinement in high gradient zones

If job exceeds expected runtime:
├── Check .sta file for increment progress
├── Reduce model size: symmetry, submodeling
├── Enable parallel processing (NCPUS = 8)
└── Switch to Abaqus/Explicit if wave propagation dominates
