Orchestrate evidence-backed ANSYS Workbench and Mechanical structural analyses through a configured MCP, including capability discovery, existing-project or CAD intake, materials, named selections, connections, loads, high-quality mesh planning and repair, solving, convergence diagnosis, deterministic validation, and report export. Use for linear static, nonlinear static, contact, modal, eigenvalue buckling, or related structural-analysis work when Codex must operate or inspect a live Workbench session instead of only explaining theory.
Use this skill when driving CST Studio Suite through the CST MCP for electromagnetic simulation workflows: creating or opening CST projects, resolving missing inputs, selecting templates, setting up geometry/materials/ports/boundaries/mesh/solvers/monitors, running or planning simulations, extracting S-parameters/far-field/near-field/eigenmode results, validating outputs, parameter sweeps, optimization handoff, and report generation.
CST Studio Suite 正式生产入口。覆盖 session 管理、几何建模、参数优化、仿真、S11/远场结果读取和审计落盘。当用户要求使用 CLI/runtime 执行 CST 操作时调用此 Skill。
当用户要求使用 CLI/runtime 执行 CST 参数优化循环、S11 指标迭代、多轮仿真对比时调用此 Skill。本 Skill 依赖 cst-runtime-cli 提供基础设施，不携带 runtime scripts，所有 CLI 调用走 base skill 的 uv run python -m cst_runtime 入口。
Analyze multi-body contact. Use when user mentions parts touching, friction between surfaces, bolt-plate contact, press fit, or assembly with contact.
Complete workflow for coupled thermomechanical analysis. Use when user mentions thermal stress, thermal expansion, or temperature causing deformation.

Complete workflow for topology optimization - determining optimal material distribution to minimize weight while maintaining structural performance.
Triggers: topology optimization, minimize weight, lightweight design, organic structure, generative design, where to remove material, material efficiency, design for additive
USE for: Minimize weight while maintaining stiffness, maximize stiffness for given weight, generate organic load-carrying structures
Do NOT use for: Shape optimization (surface only) -> /abaqus-shape-optimization, Learning Edition users -> Tosca requires full license
Topology optimization requires a full Abaqus license with Tosca module. NOT available in Learning Edition.
/abaqus-geometry - Design space with partitions for frozen regions/abaqus-material - Elastic properties + density (required for TO)/abaqus-mesh - Fine mesh (2-5mm typical for TO)/abaqus-bc - Fixed supports (these regions become frozen)/abaqus-load - Applied forces (these regions become frozen)/abaqus-step - Static step for stiffness optimizationUse /abaqus-optimization for detailed API patterns.
/abaqus-job - Submit OptimizationProcess/abaqus-odb - View density distribution/abaqus-export - STL export at density threshold (0.3-0.5 typical)| Goal | Objective | Constraint |
|---|---|---|
| Stiffest at weight | Minimize compliance | Volume <= X% |
| Lightest that works | Minimize volume | Compliance <= Y |
| Avoid resonance | Maximize frequency | Volume <= X% |
Most common: Minimize compliance with volume constraint at 30%.
| Fraction | Use Case |
|---|---|
| 20-30% | Aggressive (aerospace) |
| 30-40% | Balanced (general) |
| 40-50% | Conservative (safety-critical) |
| Constraint | When to Use |
|---|---|
| Minimum member size | Always (3-5mm typical) |
| Draw direction | Casting, molding |
| Symmetry plane | Balanced loads, aesthetics |
| Overhang angle | Additive manufacturing |
Critical:
With Defaults:
| Stage | Check |
|---|---|
| Base model | Static analysis runs, results sensible |
| After iteration 5 | Objective decreasing, no disconnection |
| Convergence | Objective stable (< 0.1% change) |
| Final design | Load path intact, no floating regions |
| Issue | Solution |
|---|---|
| Checkerboard pattern | Add min member size constraint |
| Not converging | Relax volume fraction, check frozen regions |
| Disconnected regions | Add more frozen regions along load path |
| Takes forever | Coarsen mesh, reduce iterations |
| License error | Requires full Abaqus with Tosca |
