Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by Cai-aa on GitHub. Read the source before you install it.

Installation

Install the Abaqus Interaction AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/Cai-aa/CAE-Agent-Hub/tree/main/Skill/abaqus/modeling/abaqus-interaction
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Cai-aa/CAE-Agent-Hub.git /tmp/CAE-Agent-Hub
mkdir -p .claude/skills
cp -r /tmp/CAE-Agent-Hub/Skill/abaqus/modeling/abaqus-interaction .claude/skills/abaqus-interaction

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Abaqus Interaction in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Abaqus Interaction on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Abaqus Interaction is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Abaqus Interaction Skill

Define contact pairs, tie constraints, coupling, and connectors between parts in an assembly.

When to Use This Skill

Route here when user mentions:

"Contact between surfaces"
"Friction", "sliding contact", "frictionless"
"Tie constraint", "bonded surfaces", "welded"
"Parts touching", "parts can separate"
"Coupling", "connector", "spring element"
"Join different meshes"

Route elsewhere:

Complete contact analysis workflow → /abaqus-contact-analysis
Fixed supports or displacements → /abaqus-bc
Applied forces or pressures → /abaqus-load

Key Decisions

1. What Type of Connection?

User Describes	Interaction Type	Key Feature
Welded, glued, bonded	Tie constraint	Permanent, no relative motion
Parts can slide and separate	Surface-to-surface contact	Friction, gap allowed
Load from point to surface	Coupling	Reference point control
Spring, damper, hinge	Connector	Stiffness/damping behavior
Adhesive, delamination	Cohesive	Damage initiation criteria

2. Contact Formulation

Formulation	When to Use
Surface-to-surface	General contact (recommended default)
Node-to-surface	Legacy compatibility, special cases
General contact	Automatic detection (explicit dynamics)
Self-contact	Folding, buckling, large deformation

3. Typical Friction Coefficients

Surface Pair	Friction Coefficient
Frictionless	0.0
Lubricated metal	0.1 - 0.3
Dry metal-to-metal	0.3 - 0.5
Rubber on surface	0.5 - 0.8
No slip (rough)	Use ROUGH formulation

What to Ask User

If unclear, ask:

Bonded or sliding?
- Bonded (no relative motion) → Tie constraint
- Sliding allowed → Contact with friction
Friction coefficient?
- If not specified, suggest typical value for material pair
- Frictionless is valid for lubricated or normal-dominant cases
Which surface is master/slave?
- User may not know - guide them (see below)
Can surfaces separate?
- Yes → allowSeparation=ON
- No (always in contact) → allowSeparation=OFF

Master/Slave Selection Guidelines

Criterion	Master Surface	Slave Surface
Stiffness	Stiffer body	Softer body
Mesh density	Coarser mesh	Finer mesh
Size	Larger surface	Smaller surface
Geometry	Flat/convex	Curved/concave

When in doubt: The coarser mesh should be master.

Workflow: Setting Up Interactions

Step 1: Identify Contact Pairs

List all surfaces that interact. For each pair determine:

Type (contact vs tie)
Master and slave assignment
Friction requirements

Step 2: Create Surfaces

Surfaces must be defined on assembly instances before creating interactions.

Step 3: Define Contact Properties

For contact interactions, define:

Normal behavior: Hard contact, allow separation
Tangential behavior: Friction formulation and coefficient

Step 4: Create Interaction

Assign contact property to surface pair in appropriate step.

Step 5: Verify Setup

Check for:

Correct master/slave assignment
Appropriate initial gap/overclosure
Contact pair is active in correct step

Common Gotchas

Symptom	Likely Cause	Solution
Contact not detected	Surfaces too far apart	Use `adjust=ON` or reduce initial gap
Severe discontinuity warnings	Contact chattering	Add stabilization, use smaller increments
Negative eigenvalue	Wrong master/slave	Swap master and slave surfaces
Overclosure too large	Initial interference	Use shrink fit option or adjust geometry
Tie not working	Surfaces not close enough	Increase position tolerance

Validation Checklist

Before running analysis:

All contacting surface pairs identified
Master/slave correctly assigned
Contact properties defined (normal + tangential)
Interaction assigned to correct step
Initial gaps/overclosures within tolerance
Friction coefficient appropriate for materials

Frequently asked questions

What does the Abaqus Interaction AI skill do?

Define contact and interactions - contact pairs, tie constraints, connectors. Use when user mentions contact, friction, tie, parts touching, or bonded surfaces.

Why use Abaqus Interaction on TypingMind?

Because you install it once and use it with any model. Abaqus Interaction is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Abaqus Interaction in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Cai-aa/CAE-Agent-Hub/tree/main/Skill/abaqus/modeling/abaqus-interaction. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Abaqus Interaction?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Abaqus Interaction?

As many as you like. As long as a model supports skills, you can use Abaqus Interaction with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Abaqus Interaction AI skill free?

Yes. It is published on GitHub by Cai-aa under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
