Plan, create, adapt, and quality-audit coin-style five-block O-grid hexahedral meshes for cylindrical CAE models. Use for software-independent O-grid planning or implementation in a selected preprocessor, including requests mentioning 钱币原理、圆柱网格、中心正方形、顶点切到圆周、结构化六面体网格, mapped square-to-circle partitions, or HEX8 meshes. Includes a generic planner and an Abaqus/CAE execution adapter; do not claim automated support in another CAE application without a matching adapter or proved live native-tool path.
Workflow skill for two-stage sizing/parameter optimization on a CalculiX shell or beam deck via the optimize_structure tool — Latin Hypercube sweep plus coordinate descent to minimize mass subject to stress/displacement or natural-frequency constraints by tuning scalar section/material/load cards. Use when an agent must lighten a CalculiX shell or beam model while keeping stress and deflection within limits, or must thin a deck until its first modes clear a resonance floor (freq_1_hz constraint on a *FREQUENCY deck).
Use when: operating the standalone ansys-cfx-mcp CFX MCP leaf directly from generic clients or MCP hosts. Covers CFX-Pre, Solver, CFD-Post, cfx_workflow, cfx_model_context, run_code, validate_code, lifecycle actions, model context, named objects, API help, and result-file discovery.

Optimize surface geometry to reduce stress concentrations. Shape optimization moves existing surfaces without adding or removing material.

/abaqus-topology-optimization/abaqus-optimization/abaqus-job| Aspect | Shape Optimization | Topology Optimization |
|---|---|---|
| What changes | Surface positions | Material presence |
| Result | Smooth surfaces | Holes, organic forms |
| Manufacturing | Traditional machining | Often needs AM/casting |
| Design freedom | Limited | High |
| Best for | Refine existing design | Conceptual design |
Rule of thumb: Use shape optimization when you have a good design with local stress issues. Use topology when starting fresh or need major redesign.
Before shape optimization:
Run static analysis to identify stress concentrations. Note peak stress location and magnitude for comparison baseline.
Ask user if unclear: Which surfaces can be modified? Which must remain fixed?
Only select surfaces that can be modified in manufacturing, are not functional interfaces, and don't have attached features.
Get maximum growth/shrink (mm). Typical values: 3-10mm depending on part size.
| User Goal | Objective | Design Response |
|---|---|---|
| Reduce stress concentration | MINIMIZE_MAXIMUM | STRESS (MISES) |
| Uniform stress distribution | MINIMIZE_MAXIMUM | MAX_PRINCIPAL_STRESS |
| Maximize stiffness | MINIMIZE_MAXIMUM | STRAIN_ENERGY |
Protect critical regions: BC surfaces, load surfaces, mating interfaces, precision features.
Common constraints: volume ≤ initial, maintain planar surfaces, mesh quality.
Set design cycles (20-30) and submit the optimization process.
| Parameter | Recommended | Notes |
|---|---|---|
| Max movement | 3-10mm | Based on part size |
| Design cycles | 20-30 | More for complex shapes |
| Mesh quality | MEDIUM | Balance speed/quality |
| Smoothing | LAPLACIAN | Prevents mesh distortion |
If not specified, clarify:
After optimization completes, verify:
| Problem | Likely Cause | Solution |
|---|---|---|
| Mesh distortion | Movement limits too large | Reduce max growth/shrink |
| No improvement | Wrong design surfaces | Verify surface selection |
| Convergence failure | Aggressive optimization | Add smoothing, smaller steps |
| Volume increase | No volume constraint | Add volume ≤ initial constraint |
| "License error" | No Tosca module | Requires full Abaqus |
