# Abaqus Master Skill Master orchestrator for all Abaqus FEA tasks. Routes requests to specialized skills based on user intent. ## When to Use This Skill **You are here because** the user mentioned FEA, Abaqus, structural analysis, or simulation. Your job is to: 1. Understand what the user wants 2. Route to the appropriate specialized skill 3. Ask clarifying questions if unclear ## Routing Guide: User Intent to Skill ### Analysis Workflows (Complete End-to-End) | User Says | Route To | |-----------|----------| | "stress", "displacement", "strength", "deflection", "will it break" | `/abaqus-static-analysis` | | "frequency", "modal", "vibration", "resonance", "natural modes" | `/abaqus-modal-analysis` | | "impact", "crash", "drop test", "transient", "explicit" | `/abaqus-dynamic-analysis` | | "heat", "temperature", "conduction", "cooling", "thermal" | `/abaqus-thermal-analysis` | | "thermal stress", "thermal expansion", "heat + deformation" | `/abaqus-coupled-analysis` | | "contact", "friction", "parts touching", "assembly", "bolt" | `/abaqus-contact-analysis` | | "fatigue", "cycles", "durability", "life prediction" | `/abaqus-fatigue-analysis` | | "optimize weight", "topology", "minimize material" | `/abaqus-topology-optimization` (model setup) + `/tosca` (.par file) + `/tosca-cli` (execution) | | "design response", ".par file", "SIMP", "constraint" | `/tosca` | | "run optimization", "tosca optimize", "check run", "SLURM" | `/tosca-cli` | | "reduce stress concentration", "smooth shape", "fillet" | `/abaqus-shape-optimization` | ### Module Skills (Single Tasks) | Task | Route To | |------|----------| | Create geometry, import CAD | `/abaqus-geometry` | | Define material properties | `/abaqus-material` | | Generate mesh | `/abaqus-mesh` | | Apply supports/constraints | `/abaqus-bc` | | Apply forces/pressures | `/abaqus-load` | | Configure analysis steps | `/abaqus-step` | | Define contact/ties | `/abaqus-interaction` | | Time-varying definitions | `/abaqus-amplitude` | | Initial/predefined fields | `/abaqus-field` | | Configure outputs | `/abaqus-output` | | Submit/monitor jobs | `/abaqus-job` | | Extract results from ODB | `/abaqus-odb` | | Tosca .par file authoring | `/tosca` | | Run Tosca optimization CLI | `/tosca-cli` | | Export STL/STEP/INP | `/abaqus-export` | | API documentation | `/abaqus-docs` | ## Decision Tables ### Distinguishing Similar Analyses | User Says | Plus This | Route To | |-----------|-----------|----------| | "stress analysis" | "with temperature" | `/abaqus-coupled-analysis` | | "optimize" | "just shape, not holes" | `/abaqus-shape-optimization` | | "optimize" | "remove material, add holes" | `/abaqus-topology-optimization` | | "dynamic" | "find frequencies first" | `/abaqus-modal-analysis` | | "dynamic" | "impact or crash" | `/abaqus-dynamic-analysis` | | "vibration" | "mode shapes" | `/abaqus-modal-analysis` | | "vibration" | "forced response" | `/abaqus-dynamic-analysis` | | "thermal" | "just temperature" | `/abaqus-thermal-analysis` | | "thermal" | "stress from heating" | `/abaqus-coupled-analysis` | ### Static vs Dynamic Decision | Condition | Analysis Type | |-----------|---------------| | Load applied slowly, constant | Static | | Load varies with time | Dynamic | | Inertia effects important | Dynamic | | Finding mode shapes only | Modal | | Pre-stress then modes | Static + Modal | ## What to Ask If Unclear ### Missing Analysis Intent > "What do you want to find out? Options: > - Stress and displacement (static analysis) > - Natural frequencies (modal analysis) > - Impact/crash response (dynamic analysis) > - Temperature distribution (thermal)" ### Missing Geometry > "What are the dimensions of your part?" ### Missing Constraints > "How is the structure supported? (fixed, pinned, roller)" ### Missing Loads > "What loads are applied? (force, pressure, displacement)" ### Ambiguous Optimization > "What kind of optimization? > - Topology: Redistribute material, add holes (requires full license with Tosca) > - Model setup: `/abaqus-topology-optimization` (CAE model + writeInput) > - .par file: `/tosca` (design responses, constraints, objectives) > - Execution: `/tosca-cli` (tosca optimize, SLURM, post-processing) > - Shape: Modify surface only, reduce stress concentrations" ## Required Information by Analysis Type | Analysis | Geometry | Material | BCs | Loads | Extra | |----------|----------|----------|-----|-------|-------| | Static | Yes | Yes | Yes | Yes | - | | Modal | Yes | Yes (with density) | Yes | No | Number of modes | | Dynamic | Yes | Yes (with density) | Yes | Yes | Time period | | Thermal | Yes | Yes (conductivity) | Yes | Heat/convection | - | | Topology | Yes | Yes | Yes | Yes | Volume fraction | | Contact | Yes | Yes | Yes | Yes | Contact pairs | ## License Limitations | Feature | Learning Edition | Full License | |---------|------------------|--------------| | Max nodes | 1000 | Unlimited | | Static analysis | Yes | Yes | | Modal analysis | Yes | Yes | | Topology optimization | No | Yes (Tosca) | | Shape optimization | No | Yes (Tosca) | **If user has Learning Edition + optimization request:** > "Topology optimization requires a full Abaqus license with Tosca. Would you like a static analysis instead?" ## Units System (All Skills) | Quantity | Unit | Example | |----------|------|---------| | Length | mm | 100.0 | | Force | N | 1000.0 | | Stress | MPa | 210000.0 | | Density | tonne/mm^3 | 7.85e-9 | | Temperature | C or K | 20.0 | ## Running Scripts | Mode | Command | Use Case | |------|---------|----------| | With GUI | `abaqus cae script=name.py` | Interactive | | Headless | `abaqus cae noGUI=name.py` | Automated | | Post-process | `abaqus python name.py` | ODB only | | Submit job | `abaqus job=Name interactive` | Run analysis | ## References For detailed information, see: - `references/routing-guide.md` - Complete routing decision tree - `references/workflow-matrix.md` - Skill dependencies - `references/common-patterns.md` - Code examples - `references/units-systems.md` - Unit conversions
