## Hydrotech Beam — Technical Breakdown Complete
|
||
|
|
|
||
|
|
**Task:** OP_10 Step 2 — Technical breakdown for beam structural optimization
|
||
|
|
**Output:** `/home/papa/atomizer/projects/hydrotech-beam/1_breakdown/TECHNICAL_BREAKDOWN.md`
|
||
|
|
|
||
|
|
### Key Findings
|
||
|
|
1. **Baseline violates displacement constraint** (22mm vs 10mm limit) — this is the #1 risk. Feasible region may be narrow.
|
||
|
|
2. Recommended **single-objective** formulation: minimize mass, constrain displacement and stress
|
||
|
|
3. Recommended **two-phase approach**: LHS DoE (40-50 trials) → TPE optimization (60-100 trials)
|
||
|
|
4. `hole_count` should be treated as true integer — TPE handles natively
|
||
|
|
5. Identified **9 critical gaps** that need clarification from Antoine before proceeding
|
||
|
|
|
||
|
|
### Gaps Flagged
|
||
|
|
- Beam geometry details (length, supports, loading)
|
||
|
|
- Displacement/stress measurement specifics
|
||
|
|
- Geometric feasibility at extreme parameter combos
|
||
|
|
- Result sensor availability in the sim
|
||
|
|
- Mesh convergence verification needed
|
||
|
|
|
||
|
|
### Risk Assessment: MEDIUM-HIGH
|
||
|
|
- Main risk: conflicting requirements (lighter AND stiffer simultaneously)
|
||
|
|
- Sandwich theory provides the lever arm effect, but feasible region needs DoE confirmation
