Project Progress — April → May
April briefing carried forward, updated for MayModWerks + HardGard WerkSys — Operational Software Platform
Active — Working PrototypePurpose-built system replacing TRAX + spreadsheet workarounds. End-to-end: bid pipeline → quoting → project management → procurement → financials. Joint platform for ModWerks and HardGard.
✓ April — Requirements
- Requirements gathering kicked off — scoping docs covering current-state analysis, data model, feature spec, and tech stack
- Joint ModWerks + HardGard requirements session held 4/28 — needs captured across both companies
- Problem defined: TRAX is a resale CRM, not a manufacturing system; parallel spreadsheets cause constant manual reconciliation
→ Next Steps
- Four Gateway demo walkthroughs with Ross — these close the milestone gates
- TRAX data migration — importer built, awaiting Ross's Stage-1 export sample
- Catwalk / Dry Cooler / HGRH / CoilGard configurators — awaiting Ross specs
⚠ Watch Items
- QBO end-to-end sync blocked on accountant sandbox tokens
- ~75 remaining tickets each need a specific external input (Ross specs, tokens, or a cutover date) — no amount of build time moves them
- ModWerks spinoff from HTS means TRAX departs with HTS — up to 12 months of shared access, but momentum matters
▲ May 2026 Update — Requirements → Substantially Built Prototype
- Built a substantially complete multi-tenant Django platform across build phases P19–P60, pushed to github.com/beneshengineering/werksys (last push May 13)
- 309 tests passing, 0 failing; 153 of 264 OpenProject work items closed — 58%, confirmed live in the WerkSysDev project
- Modules M0–M4.3 live: bid-inquiry pipeline, quoting, projects, procurement, approvals (Postgres-trigger enforced), pricing engine, AR/AP billing, reimbursements, and reporting with XLSX exports
- Live WerkTracker, an interactive Production WIP board, a QBO sync framework, and an AutoCAD bridge added
- Schema-per-tenant isolation working — ModWerks and HardGard run as separate Postgres schemas on one codebase, 264-work-package plan tracked in OpenProject
- Bid-inquiry pipeline added from the 5/01 Ross meeting — replaces the shared Google Doc, with sales-rep territory auto-routing

ModWerks Dry Cooler — Recirculation CFD Study
Active — Derate Tool LiveOpenFOAM parametric CFD study quantifying hot-air recirculation in dry cooler arrays under crosswind. Builds the engineering basis for site layout guidance and a customer-facing capacity derate tool.
✓ Accomplished
- Completed 70 CFD runs across array sizes (2×1 through 9×9), heights (10–60 ft), wind speeds (10–30 mph), and wind angles (0° and 90°)
- Built full wind speed response surface: 5 speeds × 4 configurations at worst-case 90° angle — 20 data points for interpolation
- Confirmed 90° wind is worst case (35.8% peak recirculation vs 16.6% at 0° for same conditions)
- Tested and ruled out central jet fan configurations (3×3 and 5×5 jet blocks) — no recirculation benefit
- Validated Perim80 as the best fan speed strategy: 80% fan area on perimeter units reduces peak recirculation by 8–11 percentage points vs uniform
- Delivered the HTML wind-rose capacity derate tool for 7×7 arrays — CFD response surface with 2,914 US weather stations embedded
→ Next Steps
- Run additional CFD campaigns for other array configurations to expand derate tool coverage
- Translate CFD findings into a site layout guidance document
Wind Speed Derate — 7×7 Array, 90° Wind
| Wind | 40ft Uniform | 40ft Perim80 | 50ft Perim80 |
|---|---|---|---|
| 10 mph | 10.1% | 6.9% | 3.6% |
| 15 mph | 20.2% | 14.3% | 9.2% |
| 20 mph | 25.4% | 19.4% | 17.8% |
| 25 mph | 35.8% | 27.7% | 22.5% |
| 30 mph | 44.5% | 33.0% | 32.3% |
▲ May 2026 Update
- Capacity derate tool is now wired into this briefing as a live demo — Launch Demo above
- Transient CFD (pimpleFoam) and DES vortex-shedding streamline animations developed for flow visualisation around and under the array
Key finding: Perim80 fan strategy + 50 ft height cuts worst-case (30 mph) peak recirculation from 44.5% to 32.3% — a 12 pp improvement with zero hardware cost.
Cubic Fans Cubic Fans Selection Software
ActiveWeb-based fan selection platform with admin GUI, public selection tool, and CLI for engineers and AI agents. Selects fans by duty point (flow rate + static pressure) across the full Cubic Fans / FansTech product line.
✓ Accomplished
- Selection platform live with web app, admin GUI, and CLI interfaces over a shared API
- Full FansTech catalog imported — 167 products across 5 categories, 131 with performance curves
- Single fan selection working: duty point in, ranked fan matches out (SI and IP units)
| Category | Count | With Curves |
|---|---|---|
| Backward Centrifugal | 80 | Yes |
| Forward Centrifugal | 48 | Yes |
| Axial | 40 | Yes |
| Duct | 11 | Yes |
| Pump | 2 | Yes |
→ Next Steps
- Fanwall selection — multi-fan array sizing for AHU and plenum applications (CFD integration is V2)
- Obtain verified spec data directly from FansTech to replace scraped catalog values
▲ May 2026 Update — FanWall CFD Intake
- Built a FanWall CFD intake webapp — a structured form that captures fan-wall geometry, flow, and boundary conditions and hands off to the FanSelect API
- Targets the modelling gap for compounding effects of stacking multiple centrifugal fans on smaller wall areas
- IP units throughout, per Kyle's call; both the platform and the intake form are live demos above
HardGard Linea Screen Wind Load Study
Complete — Calculator DeliveredCFD wind-loading study for HardGard Linea rooftop equipment screens. Produces design wind loads with a CFD-validated reduction versus the ASCE 7-22 tabulated coefficients. Issued 2026-05-14, Kyle J. Benesh, PE.
✓ Accomplished
- 38 distinct CFD runs in OpenFOAM v2512 — ABL Exposure C inflow, kOmegaSST RANS, steady simpleFoam
- Phase 1 methodology validation (3 cases) against published wind-tunnel data — Letchford 1989/2001, ESDU 89050, AS/NZS 1170.2
- Phase 2A — height × aspect-ratio sweep, bottom-gap and yaw 0–60° (21 cases)
- Phase 2B — L-corners, closed enclosures, upwind obstructions, equipment-inside (13 cases)
- Delivered the wind-load calculator, the C_f table, and a per-run CSV dataset
Force Coefficient — CFD vs ASCE 7-22
| B/s | C_f (Linea CFD) | ASCE 7 §29.3 | Reduction |
|---|---|---|---|
| 1 | 1.09 | 1.20 | −9.2% |
| 4 | 1.10 | 1.45 | −24.1% |
| 10 | 1.36 | 1.65 | −17.6% |
| 20 | 1.58 | 1.80 | −12.2% |
→ Optional Follow-ups
- Full real-CAD run (feet + braces) for an exact product rib factor
- Yaw on a closed enclosure for worst-wall identification at intermediate angles
▲ May 2026 Update — Study Complete
- All three study phases finished; every adjustment factor is CFD-backed or conservatively defaulted with stated reasoning
- CFD-derived coefficients run 9–25% below ASCE 7-22 tabulated values — reflecting ASCE's documented conservatism for free-standing walls, not a methodology error
- Calculator wired into this briefing as a live demo — Launch Demo above
Validation: mesh-independence within 0.28%, ABL profile preserved <1% from log law, wall y+ in range, convergence std/mean ≤ 0.2% — all CFD C_f values land inside the published wind-tunnel literature ranges.
ModWerks MW-RDHx — Rear Door Heat Exchanger
Active — Final CADData center rack cooling, 35–100 kW. Five SKUs (S35 / S45 / S60 / H80 / H100) targeting retrofit air-cooled facilities adding AI/GPU capacity.
✓ Accomplished
- Completed full engineering audit — identified and resolved 3 blocking issues, 15 fabricated data points, 17 internal inconsistencies
- Resolved fan voltage architecture: 208-240VAC facility input → 48VDC internal bus via dual N+1 PSUs (ADR-001 Rev C, final)
- Confirmed Danfoss FD83 2" quick-connect: Cv=127, resolves the coupling gap that was blocking hydraulic design
- Locked coil selections in CCSI Online — all 5 SKUs at straight water + 30% propylene glycol

- Completed full design doc set — controls spec, assembly + install procedures, pressure-drop and weight analysis, seismic anchoring, BMS integration, ASHRAE 90.4 compliance, UL preconsultation, SNMP/Redfish
→ Next Steps
- Send RFQs — get OEM pricing from FansTech, Neptronic, and Danfoss to close the BOM
- Finalize per-model BOM once fan + controls + QC quotes land
- Run PG derate passes on all coil selections (20% and 30% glycol)
- Alpha test plan ready — prototype build once procurement closes
⚠ Watch Items
- OEM pricing from FansTech, Neptronic, and Danfoss needed to finalize unit economics
- W-Class expansion to W27/W32 is strategic draft only — needs market input before committing engineering
Capacity by SKU (CCSI verified, straight water, 60°F EWT): S35 → 40.2 kW (+15%) · S45 → 47.1 kW (+5%) · S60 → 64.1 kW (+7%) · H80 → 91.1 kW (+14%) · H100 → 117.1 kW (+17%)
No material change since the April briefing — the program is gated on OEM pricing responses to close the BOM.
