A plant you can take apart.
A system you can inspect.
Modular 3D engineering, instrument commissioning and time-coupled process scenarios—connected to GFIS’s retained research evidence in an isolated localhost workspace.
Custom plant
Ten reversible assemblies, instrument ports, cutaway internals and capacity-linked inventories.
02 / OPEN WORKSPACE ↗City systems
Six campuses, five districts, shared storage, constrained gas dispatch and 72-hour scenarios.
03 / OPEN WORKSPACE ↗Measured evidence
500,400 archived SCADA records remain separate from generated plant and city states.
04 / OPEN WORKSPACE ↗Research intelligence
Retained persistence, XGBoost and LSTM comparisons; actual epoch histories, not simulated training.
One source of state, several ways to understand it.
Exploding the model is a display operation. Removing a module is an engineering-state operation. That distinction keeps an attractive animation from masquerading as working plant logic.
Operate the custom plant
- Open Plant studio. Create a new plant; select components and inspect their ports.
- Drag the exploded-view slider and enable cutaway. Then isolate and disassemble the actual assembly state.
- Assemble the plant and attach essential sensors. Set feed, temperature feedback, agitation and gas demand.
- Start and advance time. Watch inventories, energy totals and process history change together.
- Inject a required instrument fault. Inspect the latched trip, restore the sensor, reset and restart.
- Verify replay and export the complete session. Reopen it from Experiment memory.
48-hour modular plant experiments
Identical initial sizing and default process assumptions; one control intervention per variant. Outputs below were newly computed and retained on SSD. They are model responses—not observations or a validation of these kinetic constants.
| Scenario | Duration h | Biogas Nm³ | CH₄ Nm³ | Temperature °C | Gross electricity kWh | Replay |
|---|---|---|---|---|---|---|
| Reference commissioning | 48.00 | 1002.42 | 601.45 | 39.10 | 2301.19 | MATCH |
| Heating unavailable | 48.00 | 998.06 | 598.83 | 34.53 | 2292.09 | MATCH |

Organic residual = initial organics + input − inventory − destroyed − withdrawn
Biogas is derived from simulated destroyed organics and an assumed methane volume fraction; gross electricity uses fixed heating-value/efficiency assumptions. Net energy, gas cleanup efficacy and plant economics are not established.

Supply, demand, storage and link bottlenecks produce the visible city state. The scene is schematic: pipelines show topology, vehicles illustrate collection connectivity, and no pressure/compressor or vehicle-route solver is claimed. City supply profiles and custom-plant kinetics are not yet coupled.
Engineering checks that changed the implementation
- Emergency stops queue behind in-flight work; session transitions lock command targets.
- Required stale/faulty instruments trip at the completed simulation step; effective heating, feed and mixer states turn off.
- Mixing response is continuous from zero RPM, with declared uncalibrated parameters.
- Complete plant revisions publish atomically; stale revisions and mixed-engine continuations are rejected.
- Corrupt sibling sessions remain visible as unavailable without blocking healthy sessions.
- Route cancellation stops abandoned mounts; inspector labels refresh with assembly state.
Evidence retained, claims kept separate
DS-05 research observations, DS-06 historical total-biogas SCADA, dated persistence/XGBoost/LSTM predictions and saved epochs remain available. The current work did not train a new CNN, perform new LSTM optimisation, validate VFA/ALK or connect a physical plant. Existing gasification remains an educational thermochemical module.

Verification record and next gate
Generated from MODULAR_V2_RELEASE_VERIFICATION.json at 2026-09-08T17:29:22.337Z. Node v22.19.0. 17 HTTP asset/API checks passed; 46 automated tests passed. Geometry tests use real Three objects with a stub renderer; browser pixel QA is outstanding.
Next gate: desktop/mobile WebGL acceptance, followed by a calibrated read-only physical telemetry adapter, prospective shadow-mode evaluation and reviewed control authority. No AWS/DNS release occurred.
Pre-upgrade local Git tag: gfis-local-v1-before-assembly. Current stores and previous source remain retained.
