Architectural Layers & Ingress Bus

Layer 1: Physical Sensing & Edge DAQ Ingress (OPC UA Pub/Sub / MQTT Sparkplug B / IEEE 802.1Qbv TSN / 100 kHz Sampling): High-frequency edge data acquisition, time-stamped telemetry ingestion, and microsecond clock synchronization with field sensors and PLCs.
Layer 2: Real-Time Physics & Co-Simulation Core (FMI 3.0 / Featherstone ABA / Symplectic Integrators / Non-Smooth Contact Solvers): Executes non-linear multi-body kinematics, rigid-body contact dynamics, and adaptive step-size co-simulation with guaranteed energy conservation.
Layer 3: Neural Surrogate & PINN Acceleration (Fourier Neural Operators (FNO) / Physics-Informed Neural Networks / DeepONet / TensorRT): Deploys deep operator network surrogates to solve continuous field PDEs (thermal, fluid, structural stress) at over 10,000 evaluations per second.
Layer 4: Semantic Twin & AAS Digital Thread (Asset Administration Shell (IEC 63278) / OpenUSD / WebGL / Gaussian Splatting (3DGS)): Provides standardized semantic model interoperability, bidirectional closed-loop control, and photorealistic spatial visualization.

Performance Benchmarks & Simulation Telemetry: < 1.2 ms (Physics Step Time) | < 1.8% (Sim2Real Error Margin) | 1,400x (PINN Surrogate Speedup) | < 15 us (Telemetry Sync Jitter)
