Digital engineering workflows that combine physics-based or physico-chemical simulation with statistical or data-driven techniques offer predictive and extrapolative benefits of the detailed simulations along with the performance-enhancing modelling and analysis capabilities.
See the IC engine use case below involving such an integrated workflow:
Engine testing and calibration is a time-intensive process based on measurement campaigns that impact the time-to-market, associated costs, and the underlying CO2 footprint of the process.
We have combined the synergistic strengths in predictive physics-based models with high-performance statistical analysis in the form of a digital engineering workflow to enhance your in-house measurement campaigns towards a more cost-effective development. The workflow seamlessly integrates our toolkits MoDS, SRM Engine Suite, and CMCL Explorer, enabling model calibration (parameter estimation), validation (against new data), and surrogate generation for engine performance, combustion characteristics, gas phase emissions (CO, HC, NOx) and particulates (PM and PN).
The workflow is applicable to virtually all engine operating modes, i.e. Compression Ignition (CI), Spark Ignition (SI) as well as advanced low temperature combustion concepts. A so-called “digital thermodynamic twin” is developed for the engine using high-fidelity physics-based models, while embracing new technologies in Machine Learning and Deep Learning to account for the intrinsically high-dimensional nature of engine calibration.
Once fully realised, the workflow helps reduce the reliance on measurement data in engine calibration process by augmenting the measurements data with digital equivalents without sacrificing much of the accuracy. While the digital workflow runs fully parallelised on a standard multi-core desktop computer, HPC technology can also be leveraged to reap bigger time savings.
